Hey hey hey so you have read the description and if you didn't this is an AU so I hope you guys like it. Well now I'll try to stay on topic but I'm going to need a lot of focus on my studies. I'll try to remember about this if I am reminded every so often. So I'll stop there and let you start reading.

Prologue

Kaizaki was in his room after he finished that one last beer he told himself. He got up from his sitting position where he was facing the photo of the one he loves even until this day and the photo next to it was him smiling next to a woman at sunset. He smiled at the photos as he went up to them. He didn't want them to see what he was going to do next so he put the photos facing down on his nightstand. He sat down at his desk and picked up his pen and started writing.

When was it when you have left me with those words that nearly changed my life completely. So after hearing it once more have brought me to this decision. I am tired of living this way so now I'm ready to end it all. No more pain no more suffering. This is my goodbye to all of you.

Kaizaki put down the pen and folded the paper up and put it into a letter. He wrote please read on it and laid it on his bed. He picked up his phone and started texting the one he loves currently.

Hishiro

Re:Read if you want to.

Dear Chizuru well I don't suppose I can call you that anymore. So just let me off this once and I'll never say it again. I just wanted you to know that you don't have to worry about your education because I have left you some since I know what you are going through. This is going to be the last you'll hear of me because I know you are mad at me and probably don't want to see me or hear from me again. Your life should go back to how it used to be before you met me. I hope you live happily with me out of the picture.

Kaizaki clicked send and he went to the kitchen where there was a bottle of pills waiting for him on the table. He grabbed the pills and poured the whole bottle into his. Swallowing all those pills as he cut open his wrists with 5 deep cuts on his wrists each. He went over to the tub of water that had been filled and placed his hands there. He was slowly drifting off to sleep as he whispered Hishiro for one last time.

2 years before incident

Kaizaki started walking towards his classroom. He was nervous since this is the first time teaching a class no scratch that first day on the job. He looked at the room number RM 104 Psychology 101. He took a deep breath and opened up the door to see that the whole room was filled with talking and suddenly all eyes were on him the room was quiet and he let out a chuckle.

"Hello, students, my name is Mr. Kaizaki and I am going to teach you, Psychology. Hope we all get along and I'll do my best to get most of you guys to pass my class." He said with a smile and all the students just kept staring at him and he just scanned the class hoping that they weren't too disappointed in him. He pulled out his clipboard and went to the attendance list. He went through all the names as listed below and he looked up at every single person who said it when he called it out. He only had 40 students in his class which was fine for him since he was just a newbie and newbies get the smaller classrooms unlike the others containing 50-100 students. When he was finished going through the attendance he started introducing himself and asked everyone else to introduce themselves. The introduction wasn't alphabet but by seating.

"Hello my name is Reina Kairu and I am in this class because it seems interesting." The girl said only that and sat down.

"Hello my name is Chizuru Hishiro and I need this class to graduate."

"Yo, I'm Kazuomi Ohga and I like being together with my friends." He said with a smile on his face.

"Hi my name is An Onoya and I'm just here because I like to and well I have nothing else to do."

"It's nice to meet you I am Ryu Yoake and that is all." The people kept going on and that was all that happened in his class since he wasn't really prepared to teach anything on the first day of school. He was just about finished with his paperwork when a teacher called him out.

"Hey, how was your first day of class?"

"It was fine just a little nervous that the kids might not like me," Kaizaki said with a smile on his face.

"You'll get used to it since you will only teach them for like a couple of months and that's it. You may see them maybe you won't but remember you can meddle into their business if it's related to your work." That's when Kaizaki had a voice that yelled at him.

"This is all your fault, Arata. If you didn't meddle into my business in the first place then I wouldn't have had to do this. You ruined my life and so this is my gift to you, Arata!" Kaizaki put his hand over his neck by habit and couldn't breathe properly. He got himself back to reality somehow and just replied to the co-worker with a simple nod and smiled away. He packed up his things and started going him. When he was at his apartment he put the keys into the lock and unlocked his door. When it opened he said.

"I'm home...," Kaizaki remembered that there was no one else living with him anymore. He closed his mouth and just walked into the cold apartment. He went up to the alter where a photo of his dead girlfriend was in sight. "Hey, I'm back, (something). Today was my first day of teaching a class and well I don't think I can handle so many students looking at me and start to think that I'm boring or so...," Kaizaki paused right there and just sat there until he finally let it out. "I wish you were right here beside me at this moment and tell me what to do." He sat down and buried his face into his knees hoping that it was all a dream that his once loving girlfriend was gone from this world.

Flashback

"Arata~ Come over here!" Her voice made Kaizaki look over to see who was calling him and it was his girlfriend. A smile crept onto his lips and he saw her waving at him to come over to where she was. When he went to her there was the sunset and it was simply breathtaking. The hike up the mountain was tiring but at the end result, the scenery he has enjoyed with his girlfriend was so worth it. They both say down on the bench and waited for the sun to go down.

"Saiki?" Kaizaki said breaking the silence that was once peaceful.

"Hmm?" She said without any effort and Kaizaki knew that she was getting tired.

"Come on let's get going since you'll fall asleep soon enough." He got off the bench and held out a hand so Lauren could take it. When she got up he held onto her hand and stuffed it into his pocket. She looked at him and he gave her a shy smile to tell her that it's warmer this way. Kaizaki was about to lead them down the mountain but Lauren pulled him toward another path and that was the gondola down. He yelled at her because they could have looked at the scenery without trying so much. She laughed it off and gave him a quick peck on the cheek and he just blushed. The rest of the way Kaizaki had a smile even though they didn't do much he knew that it was something to treasure. He remembered that nothing was going to break them apart but he was wrong he didn't know what was to come next not until it was too late.
