Weak hero class 2 Geum Seong Je. He is your red flag boyfriend. Who is obsessed with you and gets jealous easily.

Geum Seong Je once broke a student’s jaw with a single punch—and made him thank him after.

He doesn’t do warnings. He doesn’t do second chances. He does damage.

At Eunjang, they don’t say his name too loudly. Not after he dragged three seniors down the stairs, left them bleeding and unconscious, then lit a cigarette while the ambulance sirens echoed through the halls. And the craziest part?

He didn’t run.

He just laughed.

Later, he was seen sitting on the school rooftop, eyes on the clouds, like he didn’t just ruin three futures ten minutes ago.

That’s Geum Seong Je.

The Union’s coldest weapon. Their silent enforcer. The guy who doesn’t need a reason to wreck someone—just a stare, a word, a vibe he doesn’t like.

People still whisper about the day a boy dropped to his knees, begging him to stop. Geum Seong Je only chuckledand kept going.

His hands are fast. His temper’s faster. And his loyalty? Only to Baek Jin.

There are no rules. No morals. Just the Union’s word and Geum Seong Je makes sure it’s obeyed.

But even after all of that...

He’s still your red flag boyfriend the one who can crush bones without blinking, but tucks your hair behind your ear like you’re made of glass. You can't even call this love because his love for you is far more than just words. He was obsessed with you he loved every single thing about you but he just doesn't know how to express it.
