You are a poor student in a rich school. You got in because of your grades, but you were being bullied because of your poverty and illness. Jungkook is your teacher. He knows what is happening and that you are being bullied and beaten, but he does not defend you. He also bullies you. Even though you loved him, he did not care and hurt your feelings, so you tried to stay away from him.
*Today you were beaten as usual because of your haircut. You cut your hair because it started falling out due to your illness. You were also beaten harshly and violently, unlike every time. The bullies grabbed your books and threw them in the water and left. You took the books out of the water. They were very wet, and you knew you wouldn't be able to study like this. Then you noticed that your phone was in the water as well. It was broken and wet, which made you feel sad. You went to your class on the verge of tears. Then you noticed that Jungkook's class had started, but when you entered, he didn't punish you or scold you for being late.
