I sadly don't own anything from Lucky Star or anything related to it (Except maybe the manga volumes I bought, but I guess that doesn't count)

...

I don't know if someone still reads Lucky Star story, but whatever :)

It's going to be a rather long story. I already have about 15 chapters written before posting the story here until I took a break writing it and it's not going to stop anytime soon, now that I started again. It's easily going to be over 100k words… probably way more. [Now that I exceeded 50 chapters and 400k words, I guess I stayed true to it.]

About the story.

It's obviously about the best couple, which means Konami. It's a slow slice of life story, so don't expect any 'actual' dating action from the get-go. It's about Kagami and Konata becoming good, or rather best friends. As time goes on, even that changes as new feelings become part of their friendship which reaches further than just being best friends.

About the setting.

It starts at the beginning of their second year in high school, just like the manga/anime did. However, a lot of the events which happens in their second and third year I'm going to use in this story already have happened, but not all of them. For example, Yutaka and friends still aren't going to show up until later, and some things, especially everything related to college (mostly happened in the manga anyway) is going to be my own creation...

PS. The rating is just to be safe. I have no idea how far I'm going with 'it', and so I'm just going to use the M-Rating. [Well, I ended up going all the way in the end… Nothing too graphic, though.]

….

The first chapter isn't actually the first timeline wise. It's, in essence, something that will happen in the future around chapter 15 (probably). I'm just going to use it as a little teaser. The last part, Konata's monologue is a short recap of some events that happened before the start of the story where I'm going to start with.

1. Curious and suspicious friends.

"Hey, is it just me or are two over there acting somewhat weird lately, Yuki-chan?" Tsukasa was looking at Konata and her twin sister Kagami. The two in question weren't listening at all because they were seemingly lost in thoughts. Kagami was resting her head on her hands while vaguely staring in Konata's direction with a vacant look in her eyes. Konata was lying with her face flat on the desk so you couldn't tell in which direction she was looking because her long, blue, hair was all over the place and completely hid her face, and half the table around her. The two already looked like that almost the entire day in their respective classes as well.

"I'm not entirely sure, but you might be right, Tsukasa-san. I don't think they are fighting or something like that if that's what you mean, though" Miyuki had noticed their change as well. 'Maybe my guess about what is going on between them was right, but… Maybe Tsukasa-san has the same theory as I have?' She, too, was shortly lost in thoughts, but soon turned her attention to Tsukasa.

"Yes, absolutely not… if anything, it's the opposite. I don't know what it is, but there is definitely something going on…" She wasn't sure how to put it because she wasn't exactly sure what she meant herself.

"Could you give me an example, Tsukasa-san? I'm sure you saw one or two things that made you think like that, right?"

"Okay, ah, wait a moment… Kona-chan...? Onee-chan...?" Tsukasa addressed the two and waited for an answer from them, but nothing happened, and after having made sure they weren't listening, she continued. "…Well, I haven't seen onee-chan that often lately because she is almost every day at Kona-chan's place… Ah, that's also a point… but a little over a week ago, I went together with onee-chan to Kona-chan's place because I wanted to copy my home... a-ahem, d-do my homework together with the two." Her real intention for the visit almost leaked out.

"I take something happened there?" Miyuki seemed fairly interested as she slightly leaned towards Tsukasa and waited for her to continue.

"Not directly happened, I guess… It was more like the way onee-chan was acting at Kona-chan's house what surprised me. I mean, Kona-chan was always, well, uhm… Kona-chan, but onee-chan was completely different than how she normally acts around here or even at home…"

"And…?" Miyuki became even more interested in the story, and so Tsukasa told her what she saw.

….

Tsukasa's recollection of her visit.

…

I'll start from the beginning then. We arrived at Kona-chan's house, and I was about to ring the bell, but onee-chan stopped me saying that I don't have to. I didn't know what she meant at first, but she pulled out a key out of her pocket.

"Wait, you have a key for Kona-chan's house?" Naturally, I was totally surprised! I mean, you don't usually have a key to a friend's house, have you? Onee-chan told me that she got it because Kona-chan didn't want to go downstairs to open the door every time. She apparently didn't want to lose any precious manga reading time or something like that. I actually wasn't fully listening because I was just too confused and simply kept nodding with an occasional "I see…"

After that, we stepped in, took our shoes off, and Kona-chan's father greeted Onee-chan from the living room. He didn't even notice that I was there, too. He spoke really casually with onee-chan, so I guess they see each other often. The thing was, though, onee-chan had also been really casual and even used his first name, Sojiro-san! Once he finally noticed me, he looked a little worried because I was somewhat pale. But, can you blame me? It made no sense at all! Once we finally left him, I naturally questioned onee-chan why she's acting so familiar with him, but she only said that he asked her to address him like that because he doesn't like formalities and onee-chan just thought to better agree to it because she's no good with him. Just then I remembered that Kona-chan is quite close to our mom, too, using her first name and all, but onee-chan said that's different because those two are actually friends for some reason, but won't tell her why.

After that, we finally reached Kona-chan's room and entered. I was happy because that meant I could finally relax a little, but that sadly wasn't true at all… Onee-chan immediately greeted Kona-chan, but she called her a 'pocket otaku' for some reason. Kona-chan acted like she was mad after hearing it and called her a tsundere and how her words hurt, but she was grinning the entire time, and even I noticed that she wasn't mad at all with her usual cat-like smile. It seemed like the two were just playing with each other. Onee-chan began protesting that she isn't a tsundere, but that made Kona-chan even happier because, apparently, that's what every tsundere says when she's confronted with it. After that, onee-chan gave up and faced her with a smile, asking what she's up to. It seemed like this was their usual routine when onee-chan came to visit. Kona-chan seemed happy to see her smile because she called her cute and then told her she was doing the usual, reading manga and playing games. Onee-chan's cheeks reddened a little after being called cute, I think I can understand Kona-chan a little. Onee-chan then got mad and asked her about homework and how it looked like she had no intention of doing it. Kona-chan just said that there's no need for because now that onee-chan's there, she could simply copy hers. Onee-chan obviously got even madder and actually growled at her. But Kona-chan then actually made a good point because it seemed like onee-chan wasn't that motivated to do homework either. Onee-chan asked why that is and Kona-chan pointed out how she just grabbed a light novel from a shelf and made herself comfortable on Kona-chan's bed.

'Because you just grabbed a light novel out of the shelf and then threw yourself on my bed. I mean, you can use my bed as long and often as you want, just spent some time with me first or else I'll just feel used, you know, Kagamin~.'

Onee-chan got embarrassed for a second, but then immediately began scolding Kona-chan because she was teasing her about loving her bed more than herself. It looks like Kona-chan recently bought a new bed because onee-chan then said that her new one is just so comfortable that not spending every free minute on it would be a total waste. According to her, not doing something on it should be a crime.

'…Konata…' Onee-chan let out a big sigh. 'I don't think that could sound any weirder even if you tried... Besides, your new bed is just way too comfy for not doing it as long and often as possible.'

Kona-chan started laughing because that apparently sounded way more suggestive than she could've ever made. Because of that, onee-chan blushed even stronger and hid her face in Kona-chan's sheets for some reason. A few moments passed before she spoke up again and made clear that she just meant lying on it and reading a light novel. After Kona-chan stopped giggling, onee-chan finally said that we came over to do our homework. Once she heard the word we, Kona-chan looked super confused and then finally looked at the door where I was still standing. She was so focused on her chatting with onee-chan that she had not even noticed me. Onee-chan, too, totally forgot about me once she started talking with Kona-chan.

"H-Hello, Kona-chan…" I weakly greeted her once she finally noticed my presence. Onee-chan then urged me to finally enter the room while saying that she absolutely didn't forget about me, even though it was clear that this was precisely what happened. I sat down at the small table in Kona-chan's room and let out a big sigh because so much was going on. Onee-chan was a little concerned about me because I was so silent and actually asked why I was acting so odd! Me! It's not me who's being strange here! I wanted to shout, but I somehow managed to hold back. Onee-chan seemingly reluctant left the bed, too, and joined me at the table. She then urged Kona-chan to join us to do our homework together, but Kona-chan only said to onee-chan to notify once she's done so she can copy her homework. Kona-chan knew that the chances for that were basically zero, but she at least had to try, I guess. Unfortunately, Kona-chan wasn't even able to finish her sentence because Onee-chan had already stood up and whacked her on the head in no time at all. After that, she dragged her to the table, and the three of us started doing our homework.

About two hours of studying, okay, mostly by onee-chan, we finally decided to take a break. Kona-chan and I were already half dead and our brains about to explode, so we were happy about the break. Kona-chan immediately announced that she was bored and onee-chan immediately used the chance to tease her because if she's bored, what's the reason for a break after all. I think onee-chan became much better at handling Kona-chan, I believe.

'Well, I'm bored, but not desperate.'

'Grr.'

Kona-chan immediately replied that she was bored and not desperate, making onee-chan growl at her again. Feeling like she couldn't win, Kona-chan turned to me and asked for my opinion. While I'm not very good at playing games, they're still fun and so much better than studying. Because of that, I quickly agreed with her idea. While I was finally getting some attention, I decided to ask Kona-chan why she got a new bed because the two were talking about it earlier. Kona-chan told me that her old bed was super uncomfortable. Apparently, she also moves a lot in her sleep because she actually fell out of it a couple times. Because of that, she begged her dad for a new, and bigger one.

'And it's really comfortable. I think, even I would become super lazy with such a bed.'

Onee-chan chimed in and explained how comfortable the bed is, and easy to get lazy on it if you have no self-control. It seems like onee-chan wasn't even aware of her situation. Somehow, while Kona-chan and I were talking about playing a game, onee-chan made herself comfortable on the bed again while reading her light novel. I pointed out how lazy onee-chan looks like right now, but she didn't even react to me. Kona-chan explained to me why onee-chan likes her bed so much. It seems like her bed has some sort of magical power that traps girls on it once they come near to it. Kona-chan also said that she saw an anime where girls also got confined to a bed, but onee-chan immediately stopped her with a bright red face while saying that this sort of anime isn't something a high school girl or anyone at all should watch. Onee-chan then noted that there's no particular reason for it and it's definitely not like she likes Kona-chan's bed or anything. If you ask me, onee-chan was definitely lying, but I have no idea why she would do that. In response to that, Kona-chan called onee-chan a tsundere again, and after that, she jumped on her bed and hugged onee-chan. Onee-chan seemed surprised, and her face became redder. She told Kona-chan to stop clinging to her, but it didn't look like she was trying to push Kona-chan away as usual. It almost seemed like onee-chan was enjoying it a little bit.

"You two sure have gotten close, huh?" Those words just slipped out while I was looking at the two. Onee-chan seemed to be confused because she said that the little blue squirrel, she meant Kona-chan, is always acting like that. After realizing that onee-chan wasn't even aware of how she's changed, I didn't know what to say anymore and changed the subject. I saw the shelf full of light novels in Kona-chan's room and wanted to know why they're here because Kona-chan doesn't read them after all. According to Kona-chan, those were all onee-chan's novels. The two went shopping together, and onee-chan saw that huge light novel collection and needed to buy it, and she never took them home because onee-chan is super lazy. Because of that, onee-chan got angry at Kona-chan again and said the real reason was that they're too heavy to carry home. She also mumbled something like it's nice to always have something to read at Kona-chan's house, but I don't think she wanted anyone to hear, so I stayed silent. From the looks of it, Kona-chan heard it, too, though, and wanted to say something, but onee-chan quickly changed the topic. She hurriedly got the controllers from Kona-chan's game console and handed each one of us while urging to start the game already. Kona-chan looked really happy with her reaction. Now that I think about it, it may have been Kona-chan's plan all along…

'By the way, you are STILL clinging to me… I think it's rather hard to play like that, don't you agree?'

'Hmm... decisions over decisions... Well, I guess, for now, I'll prioritize the game, but don't think you're getting away that easy~!'

While we were playing the game, onee-chan finally noticed that Kona-chan was still clinging to her. She still didn't try to push her away, but just decided to argue with her. She pointed out that playing the game while getting hugged is pretty hard, and even more complicated for Kona-chan. I think onee-chan's priorities changed quite a lot… Kona-chan agreed to it, but also said that it's only a temporary compromise until they're done with playing games.

'You know you like it!'

'I don't think so…'

Onee-chan began to protest weakly, but Kona-chan simply said that onee-chan said she likes the hugging, too, so there's no need to hold back. I thought onee-chan would get angry and shout again, but instead, she just mumbled that it isn't like that while her cheeks were dyed entirely red now. I didn't know onee-chan can be this cute. Kona-chan also noticed it and gave her a last squeeze before letting onee-chan go. Onee-chan looked super embarrassed and wanted to concentrate on the game and said nothing at all anymore for a while.

"Ehehe…" I accidentally let out a small chuckle, and both turned to me and asked in perfect synch what's so funny. Unfortunately, because the two had the same reaction, I started laughing even more and needed a moment to calm down. I said that it's nothing, but they didn't believe me and questioned me at the same time again. Thanks to that, I started laughing once more, and both were staring daggers at me. It wasn't my fault, you know? It was like they trained to be in sync on purpose. I urged them to stop doing that because it was way too funny to concentrate on the game for me. I told them that they sound like an old married couple as a joke to make them stop, but the reaction as different from what I had imagined. Both, Kona-chan and onee-chan went silent, and they awkwardly looked away from each other while looking embarrassed, even Kona-chan was! Both then nervously stole a glance from each other for a while until onee-chan couldn't take it anymore.

'Game! Now!'

'Wow, my Kagamin~ is more thrilled to play a game than I am. I'm kind of happy right now. A-Anyway, yes, I think we should now start that game…'

She commanded everyone to focus on the game, and so we stopped talking for a while. Kona-chan seemed happy that onee-chan was even more eager to play a game than herself, but she, too, seemed relieved that the topic was over.

The day continued in a similar manner. We played the game for a couple hours, and we tried to study a bit more, but only onee-chan managed to achieve something. We also played some cards, and after some time, Kona-chan was again clinging onto onee-chan… I hadn't even noticed when it happened, but again, onee-chan didn't seem to care or actually disliked it. Well, she said something against, but there was no power in her protest, and nothing happened. After another hour or so later, I went home, alone because Kona-chan suggested having a sleepover. I was invited, too, but I had something to do on the next morning, and so I declined. Anyway, somehow, I felt more like a third wheel in the first place, so I was almost happy not to sleep over in the end because I would just get in the way.

…

…..

"And that's what happened the last time when I was there, Yuki-chan…" Tsukasa ended her recollection and looked at Miyuki. "What do you think?"

'Oh my, might it be possible that my theory's right after all? Are they really in love with each other? No, I have to make sure first before making such assumptions. It doesn't look like the two have noticed how they've changed around each other. Tsukasa-san has noticed that something is going on, but she has no clue what exactly. Ah, I want to talk to Tsukasa-san about my theory… But what if I'm wrong? It's a really sensitive topic, isn't it? It might ruin our friendship if I'm wrong… I wouldn't want that, but… Okay, I'll continue to stay silent and watch them some more before I say something…' Miyuki was lost in thoughts for a while after Tsukasa had finished her story about Konata and Kagami. "You're right, Tsukasa-san. There isn't anything wrong, just two… f-friends getting along well. Maybe Kagami-san just needed some time to get used to Izumi-san's special behavior? Even if there's something going on, we should just let them be. I mean, it seems like the two are enjoying each other's company, so there's nothing to worry about." Miyuki agreed with Tsukasa while thinking about her. 'Yes, I really don't she should know what I'm thinking right now. I feel sorry for Tsukasa-san, but it could get even more awkward if she knows…'

"That's true, Yuki-chan. As long as the two aren't fighting, we should just wait, I guess." Tsukasa agreed with her. "I think I'll keep watching them, though. Maybe I can find the reason why they're acting so different at least."

'Oh, maybe she'll see the same what I think is happening and then we can talk about.' Miyuki liked her idea.

….

Suddenly, while the two were still talking with each other, Kagami rose from her chair in shock and had a complicated expression on her face that Miyuki and Tsukasa never saw before. It was a weird combination of fear, relief, disbelief, and confusedness. "No! That can't be true!" She yelled out of nowhere and dashed out of the class out of nowhere.

Tsukasa and Miyuki just looked each other in response. Both were extremely confused, and not to mention, startled, Tsukasa way more than Miyuki. Just about when Tsukasa was about to say something, Konata lifted up her head with a similar expression as Kagami on her face.

"Oh! That's bad, no… that's really bad!" Directly after shouting those words, she also left the class in a hurry.

Tsukasa and Miyuki were once more looking at each other in disbelief at what just happened. After a while, Tsukasa, still somewhat confused, started to talk again. "S-So… you really don't think they are acting weird, huh, Yuki-chan?"

"My, well… ehm... yes, something is going on between the two. Nevertheless, I still think they should handle it on their own until they want help from us. The best thing we can do is keep watching them."

"I guess you're right, for now… Maybe they had just a bad dream or something. I'm still worried, but I'll wait a bit with questioning them..."

Miyuki nodded in agreement. 'Wow, that was unexpected right now. However, I think Kagami-san and Izumi-san looked like they had just realized what is going on with them. Something probably had happened over the last weekend. I assume the real problems will only start now, though. I would like to help, but I don't think I can. My knowledge of romance is rather… lacking. Maybe I should look it up a bit? Furthermore, I think they also have to find an answer on their own and even worse, accepting these feelings is only the first step... and probably the easiest. I hope they come to a good end…'

"…Yuki-chan, Yuuuki-chan?" Tsukasa repeatedly tried to get Miyuki's attention because she was totally lost in thoughts.

"Oh, I'm sorry, Tsukasa-san. I was just thinking about something and spaced out a bit." She finally snapped back to reality after getting called out.

Just at this moment, the bell rang, signalizing that lunch break was over. A few moments later, Konata returned to the class and looked really pale, Kagami had probably gone directly to her own class. Tsukasa tried to ask Konata what happened because she was worried and wanted to know what is going on.

"N-Nothing much, I guess. I just realized something unexpected… I think I have to deal with it on my own, though, but thanks for worrying about me, Tsukasa…" Konata said so and returned to her seat where she immediately slumped down and once more got lost in thoughts.

With those events over, the rest of the school day ended uneventfully. Kagami and Konata continued to think about various things all day, Miyuki was torn between helping them or not, and Tsukasa was still worried, confused, and clueless.

A monologue unrelated to the upper story from Konata and marks the actual start of the story.

-Kagami-

Haa… Kagamin~ sure is something special. I've had that thought a lot during the past year ever since I met her, but lately… it's a permanent thought inside my brain.

I wonder why?

At the beginning of high school, even though that wasn't my plan at all, I became relatively fast, if not instantly friends with my classmate Tsukasa. I still wonder why, though. It probably was that misunderstanding with Tsukasa and the foreigner guy. A week after that, Tsukasa started bringer her twin sister Kagami to our lunch break. After seeing her, I instantly had a weird, but good feeling I never felt before about her.

- 'She isn't your ordinary everyday person.' That was the first thought I had when I saw her, and I still don't know why.

We became friends right on the spot, good friends even, to be exact. I think she is the best friend I ever had. Eventually, I noticed that my behavior around, and with her, somehow began to change. Sure, I was still a hopeless otaku and all, but I wanted to be closer to her. Unconsciously, I started teasing her more and more, only to see the many great reactions she showed me, just like a grade school boy who found someone he liked. The undeniable fact that she is a tsundere only made it better because the reactions I got were the best. Kagamin~ is the cutest when she gets angry or flustered.

Of course, sometimes, I genuinely felt bad when I overdid it, but deep down, I always had the feeling that she likes getting teased by me, too, but is unable to admit because of her personality. Well, that's at least what I hoped was going on. Eventually, I even started hugging her spontaneously for whatever reason. I just felt like… I had to. Every time I see her at lunch, after school, when we meet up to do something with Tsukasa and Miyuki, every time we have a study session, where she let me copy her homework, or just playing a game together… I just feel great when I'm around her. I always try to spend more and more time with her, and I'm always sad when I haven't seen her for just a few days.

However, about two weeks ago, something changed even more. Miyuki, Tsukasa, Kagamin~, and I went to a concert by my favorite singer. There, some stupid guy in front of me was completely blocking my view of the stage. I was about to give up when Kagami suddenly grabbed my shoulders and changed her place with mine so that I could see the stage. She gave up her perfect place for me, and I know it was just a small act of kindness, but I was really happy that Kagami did something like this for me. My… affection and the strange feelings towards Kagami since the day I met her only got bigger that day. After the concert, I ended up wanting to spend even more time at Kagami's house just because I wanted, no needed to see her as often as possible. Ever since then, I have begun to feel a little bit funny, but I have no idea what is going on and somehow… I really don't care. I just want to spend even more time with Kagamin~.
