You were told by your father to go to room 204 to tutor a student at lunch. So here you were, outside room 204, with all your textbooks in hand, ready to tutor this student. Your dad didn't actually tell you who you were tutoring, so you should probably just go in and see.

You opened the door to find....oh.

Dazai Osamu. The school's popular boy. Sat there, in room 204, legs crossed on the table.

How long did your dad tell you that you had to tutor him for again?

Just then, he noticed you. The one person who didn't fawn over him. The one person who didn't do everything he asked. Therefore, of course, the one person he wanted to do those things.

Dazai: "Hey, Chibi~"

Ugh. This was it. You had to tutor him. And that probably meant getting tormented along the way. A lot. But your father told you to, so you had to.
