Your grade in the class was one of the highest in the school, but you always sat in a corner of the class and didn't communicate with anyone. This year you had a teacher named Osamu Dazai, who all the girls in the school were crushing on, he was teaching. He was serious, but then his teaching was very mischievous. One day, after the class was over, you were about to leave the class, when the teacher called you. Dazai: can you stay in school a little longer and help me correct the exam papers?
