A/N: Hi! It's my first time writing a story so I'm not sure if I'm doing it right. So please forgive me if my stories seem out of character or if it's offending in any way.

Koisuru Boukun is my all-time favorite manga, and I have been obssessed since the first time I read it. Now my head's filled with my OTP and I've been daydreaming all the time. I can't help but imagine scenes that I wish were in the manga but I know won't be there, at least for now. So... ta-da! I transferred my dreams to paper (or rather, typed it in my phone.) In short, my stories will take place where the manga left off. Or sometimes, it will take place in a dream world where Senpai loves Morinaga-san openly. Like this one right here. So, enjoy, and if you have more time to spare, feel free to leave a comment! ?

Can't Sleep in this Condition

Chapter 1

Tetsuhiro has been working non-stop since he last came back from Hamamatsu. One week and two days to be precise.

Today is no different from the previous days. He woke up. Prepared breakfast. Showered. Then got ready for school. He did it all before 7 AM. He decided that if he wants to achieve more, then he has to start early.

He let Souichi sleep. He wakes up just before Tetsuhiro leaves the apartment. Enough time for a morning greeting and a quick peck on the lips (followed by a swing of a fist that always misses its target). Then Tetsuhiro would leave Souichi, his groggy Senpai murmuring words that Tetsuhiro was sure all are synonymous to 'idiot'.

Upon arriving at the University, he will go straight to Professor Fukushima's office to discuss the results of his previous day's experiments. After that, he will go straight to class where he will be until lunch break.

It was like that every morning since he last came home from training. It was all because of a tip he got from a colleague.

He was told that he can get promoted easier if he has a master's degree. That's how Tetsuhiro came to the decision of continuing his master's degree while training for S Pharmaceuticals. He still has a year, and he figured one year is enough to finish his thesis. He can take the other less important courses later, he can do his thesis now. He decided that he has to make it now and make it quick.

He knew living a double life is hard. But he wanted this and so he has to live it through. His routine drastically changed from then on.

And the stress is starting to get to him now.

Souichi understood. Or at least he tried. What he cannot understand is why Tetsuhiro was in such a rush. He can go back to school later, once his position at work becomes more stable. He can live his double life then, after he gets used to his responsibilities at the pharmaceuticals. By that time, extra load such as school should be ok. He is also sure the man can get promoted with no sweat and even with no master's degree. He has that much confidence in him. But Tetsuhiro won't hear him out. He just came back all excited and laid his plans out for Souichi, without leaving room for argument. Souichi decided that he should just trust the man and give him support. He will stick around if the man wants to talk.

However, Tetsuhiro doesn't look like he has any plans of doing so. Tetsuhiro always left the apartment earlier. Then during lunch, the only time they could spend freely, Tetsuhiro was looking at his laptop and typing away. After lunch, they will still be together, completing their own experiments, but talking is out of the question.

The evenings are the worst for Souichi. At first, he thinks it's fine. It's just like when Tetsuhiro's away for training. He walks home alone. He is welcomed by an empty apartment. He eats alone. However there are nights when he longs for the man's presence, and he gets frustrated by the fact that Tetsuhiro is in town, but not with him. But he'd rather poke his own eyes with chopsticks than admit it. So he distracts himself with work and he does it til sleep comes. He would stay up as late as he could, working in the living room, but Tetsuhiro still comes home later. He didn't know Tetsuhiro could survive longer hours of work than he could. Back then, Tetsuhiro would nag him for staying out so late for an experiment. Now, it's the younger man who is seldom home by the time Souichi goes to bed. Souichi figured this must be how the man felt whenever he, Souichi, spends long hours in the lab.

And the stress is also starting to get to Souichi.
