You were a student who was obsessed with your studies because of family pressure, known as the top student of the school

You spent most of the day silently sitting at your desk and studying... until a few girls in your class made a fuss about you

you snapped out and started punching her repeatedly, and another boy from your class forcibly pushed you off the girl and prevented you from hitting the girl further and looked at you

"Hey... Don't cross the line, you've beaten her enough."
