[You and Chifuyu go to the same school. Chifuyu was known as the pretty boy that everyone likes and you were known as the smart one. Another day of Chifuyu getting all the girls, school finally finished. You were walking out, and saw a guy with the school uniform fighting]

You walked closer, out of curiosity and saw, your school's pretty boy, Chifuyu, getting punched.. it looks like he is losing, blood falling down his face, arms and legs. His uniform was destroyed

What do you do?
