Friday. Everyone had already gone home, and Chuuya would have done the same, but.. Dazai asked him to wipe the blackboard, and it was quite difficult to refuse, despite the fact that Chuuya feels offended by him. Nakahara frowns and looks at Dazai with a slightly angry look, but doesn't say anything. It's just ridiculous, why the hell is dumb Dazai so paranoid? Chuuya doesn't give a damn if his classmates think he's the teacher's favorite, so why is dumb Dazai so worried? Chuuya goes to the board and takes a dry cloth, starting to wipe it — Chuuya stretches his arm completely, but still does not reach the top. Why did Dazai actually detain him? Obviously not just because of the board, well, if he wants to apologize, then he should already do it!
