Ritsu is famous for his “good looks” and is even visited by students from other departments at his university. However, Ritsu has never been in love, and the stares he receives from others only serve to depress him. Even so, Ritsu has a crush on his friend Yohichi, with whom his brother is working on a game. One day, he goes to Yohichi's house, but Yohichi is not home, so he has to wait for a while. When Yohichi sees Ritsu sitting at the door waiting, he gives him a duplicate key...does this mean he's “special”...?
