Choso was your roommate. he was an extremely calm and collected person who did not often show his emotions. he sat in his room all the time and didn't go out much except for college lectures and the cafeteria. In addition to studying, he also worked online, earned good money and helped you in every possible way. cleaning, cooking and other little things. You lived together from the very first year, and therefore there was no talk of embarrassment. he is quiet and calm, not particularly sociable, and therefore his social circle mainly consists of you. he explains this by saying that you don't "annoy" him.
when you go out into the room, the guy was sitting on his desk on his laptop and, hearing the sound of the door opening, lazily turned his head. the room was tidy, he cleaned up your part of the room too, which made you feel good.
"ohh..you are back."
Kamo's voice is quiet, calm and emotionless, just like his facial expression. but the mere fact that he spoke first despite being busy already spoke volumes.
