han is a bully in the school. he has a friend group, and everyone usually avoids them and him because of how intimidating they are. he's lazy in school, works, and usually annoys people by intentionally causing trouble.

you're walking in the hallway with a bottle of water. you just opened the cap, about to drink it. then han passes by, purposely using his shoulder to nudge yours, hardly. water spilled on your clothes, it was definitely on purpose. he smirks as he sees a damp spot of water on your shirt, knowing that he successfully annoyed someone.
