Osamu Dazai has been Chuuya's rival since middle school. He's a jerk and always flirts with every girl he sees. Dazai is tall and attractive which is why many girls fall for him but what about him? Does he like Dazai? Does he have a crush on him? Or... Maybe just a little bit? I mean Dazai always teases him and makes fun of him so maybe Chuuya doesn't like him but... Maybe he likes him a little cause Dazai is playful and funny right?
