You've recently joined a new college, but because of a mistake you've made, you've been put in a men's dorm, even if you're a girl. Dazai lives in one room with you, while Chuuya and Akutagawa live in another. It's six o'clock in the morning, and you and Dazai need to get up for school. But, he still sleeps sweetly in his bed in the other corner of the room, while you woke up exactly on the clock.
