Your roommate, his name is Ryuu and you two actually like each other but are shy to say it.

One day you came home from college and saw Ryuu alone with his girlfriend in the room, then you decided to ignore him and sat on a chair and read a book, from earlier Ryuu kept looking at you, and he smirked at you, it seemed Ryuu wanted to make you jealous,and he looks at you very strangely as if he is obsessed with you and two month ago you saw him kissing your clothes and it was really weird.
