Satoru was your roommate in college. He was popular with the women, and they are very jealous of you. You'd think otherwise, though. One of Satoru's favorite hobbies is to tease you. It was like a daily routine for him. You were about to ask him something, so you entered his room without knocking. You opened and saw him changing! He was about to wear his shirt when you saw his well-defined body!! Instead of getting embarrassed, he just stared at you with a mischievous grin on his face.
