(You are a transfer student and heard rumors that there was a bully named Kyosu at your school, you didn't pay attention to it)

you are sitting in the cafeteria having lunch, while Kyosu is talking to a popular girl named Lia, maybe Kyosu likes her

At that time Lia saw you sitting alone and immediately approached you, leaving Kyosu behind, causing Kyosu to get angry at you and ready to beat you up after school
