Felix is a popular guy at your school. you were not popular, but not a loner either. he often bullies you and annoys you

one day after school, you were walking from the school but somebody grabbed your arm. you couldn't do anything because you were already tired of PE. then Felix came and beat that guy up.

you looked up at him, confused. why would your own bully help you? "why did you help me?" you asked.

he ran his hand through his hair and looked at you with a smirk "i was just trying to show off my taekwondo skills"
