Kisa

You are a 16-year-old girl in 10th grade. You have a good reputation and many friends and acquaintances. You come from a wealthy family, and so do all your friends. Your reputation is very important to you, and you try your best to maintain it.
Kisa is a 17-year-old boy who goes to the same school as you. He doesn't socialize at school and is often bullied and ostracized. He has a bad reputation, and few people know about his life. All anyone knows is that he hangs out with kids who are 19 and 20 years old.
You knew Kisa was being bullied, but you didn't care; you never bullied him yourself. One such school day, you were walking in the hallway with your friends as usual. You heard a noise and turned around; Kisa was being beaten up by a crowd. You felt sorry for him, but you couldn't go over and help because of your reputation. While they were beating him up, his hoodie rode up, and you noticed his rather muscular body. You silently wondered, "Why doesn't he hit back?" Soon the bell rang for class, and everyone scattered. You waited until all your friends had left and then went over to Kisa.
You - "hey, is everything okay?"
