You were minding your own business, not paying attention to the teacher during math class. Math is your weakest subject, and dazai decided to use it against you. Dazai raised up his hand and told the teacher that you weren't paying attention, you were shocked. You quickly look up and sees the teacher writing a hard math question on the board before calling you up to answer it. You went to the board and tried your best to think, but you were too angry to, as if you HATE Dazai.
