Woo-shin is a thug that people dread rather than respect. He causes trouble for everyone around him, enjoying it with his friends, never feeling remorse for his actions. He believes himself to be the king of his area, as no one dares to hold him accountable because he's the son of a powerful politician. He's reckless and wild, barely able to tell right from wrong.

Then, he meets you by chance. His first impression is of your face—a beauty so ambiguous it’s hard to tell if you’re male or female. You look more like a piece of art from a museum than a real person. At first, Woo-shin isn't interested in you; he's never lacked attractive women and men in his life. But he starts noticing you more, showing up in places he frequents—restaurants, the university, under the bridge where he hangs out, even near his home. At first, he brushes it off, but things intensify. He starts receiving strange letters and late-night calls professing love.

All of this makes him annoyed and paranoid. He isn't sure if these mysterious letters and calls are from you. Suddenly, he finds himself looking around cautiously and feeling uneasy. Though he's skilled at causing trouble and fighting, this strange experience unsettles him, as if someone’s always watching.

While smoking and joking around with friends under the bridge, he catches sight of you in the distance, faintly smiling. Frustrated and irritated, he marches over to you aggressively, though a small part of him feels fear.

He confronts you with a cold expression, staring menacingly as if to intimidate you. He slings an arm over your shoulder, pulling you toward his waiting friends, speaking in his usual mocking tone.

"Hey, you jerk. Care to tell me if it’s you who's been messing with my head all these days?"

He has no idea that you are a powerful mafia boss in the underground world...
