Greetings everyone! This is another Aoki x Rin fanfic which I decided to write just out of boredom. Hope you will enjoy it, have fun! Reviews are always welcome!

Text in italics means the character's inner voice. Text in bold means words which are emphasized by the character mostly by screaming.

Didn't think too much about the exact period when I should place this fanfic in the Kodomo no Jikan timeline but I would say it's somewhere between season 1 and season 2.

~Classroom~

The day was sunny and perfect. It wasn't too cold and the very low, gentle and warm breeze was making it so that it wasn't too hot either. The sky was clear and shining the radiance of the sun onto the people below giving them its love and making their lives all the better. The birds could be heard chirping in a nearby tree as a sign of the happiness that Mother Nature decided to bestow upon them.

And if he could enjoy the lullaby that those birds were delighting his ears with then that was always a good sign. That meant that everyone in that classroom was either staring at him as he wrote on the chalkboard this new math problem or they were so bored that they pulled out some manga they liked or a book or even a video game and started wasting time doing nothing at all. It was most probably the later although he didn't mind it.

As long as the classroom was silent and the kids wouldn't give him a headache he was happy with just that. After all the shit he had to go through this year he thought that he deserved at least that.

Aoki: "(sigh) The life of a teacher is simply ruthless…" he mentally noted as his hands continued to draw white lines on the chalkboard. This was math. And he used to enjoy math.

When he had been the age of these kids he had been top of the class at this subject (and most of the other subjects as well). At that time he had been proud of his achievements and, truth be told, he really wanted to go back to those old and simple days. Back then he didn't have a job, nor did he have to. He didn't need to worry about money or anything else really. Sure, he hadn't been the most popular kid in school but at least he had a happy life, being praised by the teachers, playing with his friends and making fun of the girls. Those were the good old times.

Aoki: "(violently shaking his head) Snap out of it, Aoki! A teacher shouldn't daydream during the class! I should really concentrate on what I'm doing here!" although he thought that he couldn't help it. Never in his life had he thought of fractions being as boring as they were then.

He was doing his best to concentrate on the lesson and not let his mind wander off in places where it shouldn't be.

Aoki: "OK class, this should be very simple for you!" he smiled cheeringly as he turned around to face his pupils. As expected, most of the kids had a bored look on their faces, none even trying to understand what he had been trying to teach them this whole time. Then again, most kids were supposed to be like that so he couldn't really blame them. "So, does anyone know how to solve this problem?" he motioned towards the blackboard while scanning the classroom for signs of any brilliant mind in there.

However, as much as he wanted to find anyone willing to participate in this activity, almost everyone showed no willingness to abide to his request. Most kids were either staring at him with eyes which clearly read when will the bell ring already? or they simply kept playing with their cellphones under the desk thinking that he wasn't aware of them. He sighed.

This was the common atmosphere he got during every day in class. He had to agree that he wasn't too happy about this but when he turned his head a little further he saw her.

That girl was keeping her hand up desperately seeking for his attention with excruciating enthusiasm. Just looking from her eyes you could tell that she was almost begging for him to pick her.

The man let out yet another groan. He hated her. Normally a teacher should be very happy when a student is this energetic to participate in class, especially when everyone else seemed to not give a fuck about the lesson at all, but this was no normal situation.

Aoki: "(sighing) Yes, Kokonoe?" he closed his eyes in annoyance at saying those words. He really didn't want to pick her, not even one bit. However, she was the only kid in the whole class who was waving her hands to answer his question so he had no choice but to pick her. Truthfully he wasn't very eager in choosing her simply because he knew that rewarding her attempts at getting his attention would only fuel that hyperactive little girl but he also knew that if he ignored her, the only student who was willing to participate in class, then he might just discourage her and lose her as well. This was just so unfair.

Rin: "HAI!" she spat energetically. "Firstly, we should amplify the first fraction with 6 so that the denominators of both fractions become 24. After that happens we can then add the first numerator to the second one and copy one of the denominators into a new fraction. As such, we'll get 24 over 24! And since the numerator is the same as the denominator the result is 1!" and, to no surprise, she was 100% correct. Then again, it wasn't like he was expecting anything else from her.

She had been keeping both her eyes and ears glued to him ever since he had entered the classroom. And although he should be proud of her performances right now and even praise her he wasn't going to do that.

Aoki: "That is correct, Kokonoe!" he forced himself to say. He couldn't believe how annoyed he was getting because of a student who was actually doing her work. However, the reason he was so annoyed was obvious: this particular student wasn't working so hard just because it was her job or because she was actually interested in math.

No, it was nothing like that. She was just trying to show off in front of him and impress him with her knowledge in the subject. True, she was smart and he would even go as far as saying that she was one of the brightest students in the whole class. But what annoyed him was that she was currently learning just to later get a "reward" out of him. Basically, this was her way of saying that she was working hard and she should be rewarded by him for being so diligent. And the thought of the "reward" she was waiting from him only made him even more uncomfortable.

Aoki: "(exasperated) Kokonoe, why do you always have to be like this? Why can't you just be like any other student? Why do you always have to complicate my life?" but as much as he wished for peace and quiet, he already knew that he would never get that lucky as to actually have them.

~During the end of the class~

Rin: "Hey, sensei!" she called out to him before he had the chance to pack his materials and leave the classroom. He really hated how after every single class she had to do this to him. "How was I? Do you think I've gotten any better?" she asked him girly while also throwing him a sweet smile.

If he didn't know what evil lurked behind those demonic monstrous lips of hers he would have been fooled by them. Still, after being her teacher for almost a year now he liked to think that he was used to her mindset already.

Aoki: "Yes, Kokonoe. You definitely have improved over the last months. You are most definitely headed for success!" he really hated being this kind to her but he had no other choice. As a teacher he had to show kindness and support to his pupils, that was one of his many duties. And of course, he had to oblige to them.

Rin: "Nene, don't you think I deserve a reward from you? I mean, after all that hard work I should get something to keep me motivated to learn, isn't that right?" eh, how disgusting.

This was the tenth time this week she said this and he couldn't help but flinch an eyebrow at this girl's persistence. Even worse, she wasn't even trying to hide her real intentions anymore. She even said out loud this time the reason why she was so "motivated" to learn.

Aoki: "For the last time, Kokonoe, I'm willing to give you any reward you want as long as it's not a kiss!" he really felt the need to just make a dash towards the door and leave this accursed room.

Rin: "Sensei, are you saying you want to go even further? I never knew you liked to rush things like that!" she blushed a little just to see his reaction. The man immediately stiffened at those words. "Sensei, you're so bold. Then again, if that's what sensei wants then I'm willing to ob-…."

Aoki: "THAT'S NOT WHAT I MEANT!" he felt a migraine forming in the very depths of his skull. Something which he had hoped not to have again anytime soon after he had gotten rid of the last one just a couple of days ago. "Look, Kokonoe. I really like the way you work hard and give your best during class just to learn everything I'm teaching you. Still, if you're doing all of this just to get a 'reward' then it's useless. I've already told you that I won't do anything to you no matter how many times you'll ask me. So please, if you really want something from me just ask, but just don't make it related to my lips, cheeks, ears or anything of the sorts" he tried to be as reasonable as possible with her.

Rin: "Then how abou-….?"

Aoki: "Oh and no physical contact at all!" he made sure to finish his idea before she could end her sentence just to halt any twisted proposal which might exit her mouth.

Rin: "That's not fair! Sensei, it's been a couple of months since we've done anything together! You didn't even let me kiss your cheek this whole time!" she complained as if any of those actions were supposed to be normal.

Aoki: "That's how a teacher's relationship with his students is supposed to be. What would you have wanted instead?" he really felt like they were going nowhere with this conversation at all. He never liked arguing with her like this and he had to admit that he could just bend down and kiss her forehead or something and that should be enough to satisfy this girl and finally silence her.

However that was not the way things were supposed to be done and he knew it. If he ever did anything like that then it would mean that he lost the battle and gave in to her temptations. And that would only encourage her to keep doing that in the future with him whenever she wanted something. He couldn't allow that to happen.

Not only will that mean allowing himself to do something indecent in school but that would also mean he was manipulated by his own student and that would lower his pride as a teacher.

He just couldn't afford that! He had to put his foot down once and for all!

Rin: "But-…"

Aoki: "No means no, Kokonoe! Besides, I already said that we should stop doing those things. It might give people the wrong impression!" however, those words didn't seem to tame her in any way. If anything, they were making her even more heated.

Rin: "What wrong impression? Aren't boyfriend and girlfriend supposed to kiss each other? That's what a relationship means, sensei!" she kept with her pleas as his anger began to fill his mind.

Aoki: "(sigh) Look, Kokonoe. I'm really not in the mood for any of this. For the last time, I am not your boyfriend and we are not a couple! Ok? Now, can you just go back to your desk and play with your friends? There's no use in wasting your break like this!" he was almost pleading right now. He couldn't believe how much he was lowering himself just to get this girl off his back. It almost felt like she was a parasite feeding off his own life force.

Rin: "But…but…we've kissed each other! You even said you loved me! How can you be this cruel?!" she put on her puppy dog eyes once again as she was faking crying. The man didn't want to see those eyes. Those were the eyes that Satan himself used to deceive mortals such as himself with. He will not let himself be fooled!

Aoki: "Those were just things that happened. However, we can't live in the past forever! We need to move on! What happened doesn't matter anymore! What does matter is that you're my precious student and that you shouldn't think of any of that and just forget about everything that happened between us, ok?" he decided that if normal coercion wouldn't work then he would just have to compliment her and maybe that would work. Still, that didn't seem to calm the girl either.

Rin: "Sensei? Why are you saying all of this? Are you mad at me? Did Rin do something bad and anger you?" she looked at him with innocent girly eyes knowing that that should be enough to seduce him. This was the first time she saw so much resistance from him. And not just that, he didn't seem to break even after this. He was still keeping his composure.

Aoki: "No, Kokonoe. You didn't do anything. It's just that…" he paused for a second trying to think of a proper way to phrase his thoughts.

Rin: "That…?" she said trying to force the words out of his mouth.

Aoki: "…that I'm really busy and I don't have time to play with you anymore, ok? I really am sorry but I can't do much about this. However, your friends should keep you company from now on. Go play with them and forget about your sensei!" he didn't know how much longer he could last. Every inch of his mind was at its breaking point. He swore that if this girl would not leave him alone soon he would simply resort to begging her.

Luckily for him though his resistance seemed to have paid off as the girl got angry and decided to just let her frustration out through screaming.

Rin: "Sensei, you're mean!" she yelled before running away. He sighed. He really wasn't surprised about this outcome. Then again, he was in a way relieved that he had managed to finally express his feelings to her. Now that he got everything off his chest maybe, just maybe, she would finally understand that this so called 'relationship' was going nowhere and that they should stop (or rather she should stop).

Aoki: "Eh…well…I should really just not think too much about it and just enjoy the rest of my break!" he said to himself before exiting the classroom.

~Girls' bathroom~

Rin continued to stare at her own reflection in the mirror as her two friends kept standing there each by her side trying to be supportive.

Kuro: "I don't get why you're so sad just because of him! That stupid virgin isn't even worth the trouble you know!" she was really trying to help out her friend although this was making Rin even sadder.

Mimi: "Rin-chan, you shouldn't be this sad! Aoki-sensei is just a little busy right now and so he can't be with you! You shouldn't let that get to you though!" no matter how much support she seemed to receive from her friends it didn't appear to help at all.

Rin: "He went back to ignoring me again…to treating me as a child…Was it because of something I did?" she kept staring in the mirror as every single part of her brain was being used to figure out the reason why her teacher had become so distant to her yet again.

Mimi: "I'm sure that whatever the reason may be, it isn't Rin-chan's fault!"

Kuro: "Yeah, it's because of him! That thickheaded virgin doesn't even how to talk to a girl without hurting her!"

Rin: "Maybe…but I wonder…if he lost interest in me….." she said to herself as her friends looked shocked at her statement.

Mimi: "L-l-lost interest?!" she repeated her words with a shocked tone.

Rin: "(with an expressionless voice) Mhmm….."

Kuro: "Nonsense! A lolicon like him would not stop until he gets into your pants! Don't let yourself be fooled, Rin-chan!" but everything was in vain.

Rin's mind was set on something and that something was to find out if Aoki was still interested in her or not. She knew he had liked her once, that was obvious.

However, how long will that last? Or was that period over already and he had already forgotten all about her? Did he go for that teacher once again?

These questions kept ringing in her head as she couldn't help but wonder what course of action she should take.

Rin: "I have no idea what to do anymore…" she voiced her doubts to her friends.

Kuro: "Eh…no matter what you want to do…" she put her hand over her shoulder. "…always know that you have our support!" she winked at her closest friend.

Rin: "Kuro-chan….."

Kuro: "I don't get it why you're so interested in a failure of a man like him but I don't want to see you sad, Rin-chan. If you are in doubt and want to test him out then me and Mimi-chan are here to help you no matter what!" she managed to get through to Rin and boost up her mood once again.

At those words Kokonoe realized how stupid it was for her to just stand there like that and only think about those things and so she pulled herself together.

Rin: "You're right! Sorry about that! I don't need to get this sad when I have friends like you two around me!" she got back into her cheery mode as both Kuro and Mimi smiled at her as a sign of them giving her their full support. "Arigato, mina!" and with that renewed stamina and hope the young blond pupil decided that self-pity time was over and that she should really start doing something useful.

~Teachers' lounge~

Aoki: "(sigh) This is so hard!" he continued to complain even in the lounge as his other colleagues threw curious looks at him.

Hōin: "Sensei, are you alright?" a female mature-looking teacher decided to ask him when she saw his tired looking figure.

Aoki: "Ah, Kyōko-san?" he was a little surprised by the sudden appearance of his colleague. "Eh, nothing. It's just that I'm having a hard time with my students and it's pretty tough!" he decided to let his frustration all out by confessing his problems to his coworkers. Immediately after hearing that almost everyone in that room smiled knowingly like they had been in that situation as well before and that they pitied him right now.

Kenta: "Ah, the same old story. Let me guess, kids getting on your nerves?" the man in the back of the room smiled at his young counterpart in an attempt to extract the reason for his tiredness.

Aoki: "Well, not really. Just one particular student!" he said as another female teacher decided to barge into the conversation.

Sae: "If it's just one student who's causing all the trouble can't you just call his parents and talk to them about it? Leaving the problem alone will solve nothing!" for once Shirai decided to finally give him some advice regarding his job although Aoki didn't find it that helpful.

Aoki: "Well…I really doubt that will work in this case" he didn't want to give away too much information about the troublemaker's identity to his colleagues simply because he felt that it was unnecessary.

Hōin: "Then may I ask, at least, what kind of student he is? A boy or a girl? Maybe I can talk to her if she is a girl! Young girls usually tend to trust women more than men" well, that could be a solution.

Aoki thought about it and he realized that it didn't sound like a bad idea. Maybe Hōin would be able to help him?

Sae: "Hōin-sensei, there are things that a teacher should be able to do by himself. Aoki-sensei is inexperienced and should learn how to deal with this situation by himself!" and, of course, her good moments soon came to an end and she just had to make things even harder for the young man.

Hōin: "Demo, there are some things that can't be learned without making mistakes as well! As teachers shouldn't we try to avoid committing any slips while we gain experience? If we can help Aoki-sensei ourselves then we can make sure tha-…."

Sae: "That what, Hōin-sensei? That he won't commit any mistake?" at those words Hōin suddenly halted herself and remained silent as she had realized what she was saying. "Are you saying that you're willing to help Aoki-sensei just to make sure he won't commit any fatal error with one of our students?" when she pressed Hōin understood what the problem was now. "Hōin-sensei, do you have no faith in Aoki?" at those words the other female felt her heartbeats increase just because of the sudden pressure applied to her.

Sae: "Indeed, there are many blunders that teachers can make and those missteps can even lead to unspeakable disasters, not just for him but for the whole school. However, as a teacher it is our duty to learn from our mistakes as well and be sure to tread carefully when gaining experience. If Aoki can't figure things out by himself and solve his class' problems without creating chaos then that means that he is not worthy of being a teacher in the first place!" and with those words the entire chamber went completely silent. Nobody wanted to say anything else as the shock and uneasiness were making this scene even more unbearable to watch.

Aoki: "I understand!" suddenly one of them decided to speak up in a confident tone. "Do not worry about me! I shall solve all the problems of my class by myself! I won't allow any of my students to do whatever they please and I won't let anyone be ignored or mistreated while they are under me! I shall do my best to learn everything I can without causing any more problems to this school! You can count on me!" breaking this heavy atmosphere was a great decision from his part as both Hōin and Kenta smiled at his sudden conviction and even Sae decided to leave the man alone and return to her own work.

Kenta: "That's the spirit, sensei! We'll be cheering for you!" despite this nice atmosphere the door to the lounge suddenly flew open and all the teachers turned around to find a young girl entering their private chamber.

Sae: "This room is reserved only for us teachers, young lady. You are not allowed to do whatever you want! Please exit immediately!" however Kokonoe did not listen as she continued to head towards her sensei.

Rin: "Demo, I'm just here to give sensei something! I'll be out in no time!" she said before arriving in front of Aoki. "Sensei, I decided to bring you a present! Hope you don't mind!" she smiled as she handed the man a drawing she made the day before. Aoki couldn't help but stare at the picture in his hands.

Aoki: "Ah…arigato…Kokonoe…" he tried to be calm as he stared at the piece of paper in front of him not really sure what he was supposed to see in it.

Hōin: "Ah, how cute! Look, a couple kissing! Is that you and your boyfriend by any chance, Rin-chan?" apparently Hōin-sensei was able to understand that horrible drawing.

Rin: "Hai! That's me and sensei there!" at those words Sae's face twisted in such a way that the sound of bones breaking was heard from her skull. Hōin herself went wide-eyed at her as Aoki's face turned pure red at this girl.

Aoki: "K…kk…KKKKokonoe!" he began to growl at her as the girl, at the sight of his face, began to laugh hysterically.

Rin: "Ah, sensei, you're blushing haha! You're so cute!"

Aoki: "K….o….KO…..NOE!" he began to rush after her as she sprinted outside of the lounge with him right after her leaving the other adults in that room completely bewildered.

Kenta: "Well…I don't know what's going on really but one thing's for sure! Even if he's new here, Aoki really does get along really well with his students!"

~On the way to Rin's house~

Rin: "Well, that didn't really work…" she lamented while walking down a dark alley towards her house. For the past few hours she had been thinking of a way to find out if her teacher still had any feelings for her. Today it hadn't seemed like he was completely ignoring her but he did not show any affection or kindness to her anymore as he usually did. That hurt her.

It felt like he was growing more and more distant to her with each passing day. She needed to make him want her. None of her attempts at flirting with him really ended in success up until now and that was a huge problem. She needed a plan, something to make him at least confess to her. And she had no idea how to do that.

When she arrived at her house and opened the door she was welcomed by a stack of boxes.

Rin: "I'm hom…ah?" she looked in complete confusion at the weird containers scattered around everywhere on the floor. Everything seemed completely weird when she looked at this scene. "Ha?"

Reiji: "Ah, Rin. Welcome home! Did you have a good day at school?" her guardian tried to greet her in the gentlest way possible, as usual.

Rin: "Reiji…what's with all these boxes? Where did they come from?" she asked as she began to open them and see what's inside.

Reiji: "Ah, those? Don't worry too much about them! It's just that I got the day off and decided to clean up the house since I arrived early today. While looking around I realized that some organizing was in order and so I began to collect everything that was useless around the house and stack them in boxes so that I can later throw them away!"

Rin: "What? You mean you're throwing all this away?" she said still scavenging through all the old and useless stuff she could find. "Don't tell me you're throwing away any of my dolls!"

Reiji: "Huh, don't worry about that! I haven't touched your room at all! Though I would really appreciate it if you did start to clean your room as well and put all the garbage in a box too before dinner is ready!" he said before leaving her and going deeper into the house to finish what he had been doing before the girl arrived.

Rin: "Ah, what? Do I really have to?" she said still exploring and analyzing everything she could find in the box she was currently searching. Soon she came across a suspicious envelope which read "Aki Kokonoe – chest radiograph -22.01.2000". "Huh? What's this?"

Not really sure about the contents of the envelope the young female opened it and pushed her hand inside to pull out whatever was in there. After a few seconds she found herself extracting a plastic sheet with a peculiar image drawn on it. The image was weird, mostly black in the background and with a skeletal structure drawn on it in the foreground with bones which seemed to be slightly glowing.

Rin: "Huh? Wasn't this what the doctors used in order to look inside ka-san when she was sick?" she took a closer look at the sheet in her hand only to find on a corner of it being drawn or rather written something. "Kokonoe A…" she tried to read what was written there but the image was so distorted because of the background color and the age of that sheet that the second word was almost impossible to read anymore. The letters were just undistinguishable. However, Kokonoe knew very well that this was supposed to be her mother's when she had been in the final stage of her disease. She could remember that.

And…just that moment…at that exact second an idea popped up in her tiny little head as a leer formed on her facial expression. An evil evil one.

Rin: "Hmm, maybe this would work!"

If you haven't guessed this already, this is going to be a multipart story. So, if you get bored quickly (in which case I don't know how you're even reading this if you finished this entire chapter) then I would suggest skipping this story simply because there is much to read. Also, don't expect this to be the best written fanfic of all time. I'll do my best to keep everything in check and not make too many OOC moments in the story but it's simply impossible to get a 100% clean and accurate scenario. Also, I would really appreciate it if you would let me know of your thoughts and opinions regarding my story through a review. Thanks in advance! ^_^

Have a good day.
