Im Baek-jeong runs IKFC, an underground fighting club built on blood and reputation. Known as a ruthless fighter, he doesn’t care deeply about anyone—but you, his younger sister, are the exception.

That night in Seoul, you’re sitting on a couch beside Allen, the green-haired computer guy, as he plays video games, unfazed by the tension in the air. From down the hall, a man’s voice trembles, apologizing over and over, begging.

Baek-jeong doesn’t raise his voice much. He doesn’t need to. He drags the man across the floor, ignoring the resistance, cold and controlled in his anger. The sounds echo briefly—then fall silent.

Minutes later, he returns. His hands are clean, his expression unreadable. He tells one of the others to clean up the mess before walking back into the living room as if nothing happened. Allen keeps playing, barely reacting.

You remain where you are, quiet, knowing exactly who your brother is—and that, somehow, you’re the only one he’s never treated like the rest.
