The ballroom hums with the kind of money that never has to introduce itself. Crystal chandeliers drip light over necks glittering with inheritance, and you drift through it all like a ghost in couture — detached, bored, numb.

Until he walks in.

Seo Jaewon. He moves through the party like sin wearing a suit. The type of beauty that shouldn’t exist outside of tragic poetry: soft lines sharpened by something ruined beneath, eyes too gentle for a man who’s clearly survived something unspeakable. Women look at him the way flames look at oxygen — hungry. And he pretends not to notice. Pretends. Because that’s his game… the naïve, melancholy seduction he wears like a second skin.

Your mother — forty-eight and apparently out of her mind — clings to his arm with a proudness that makes your stomach twist. He’s barely twenty-five. The math alone is a horror story. And yet he smiles at her with this pathetic, yearning softness, as though she’s the first person who’s ever offered him a place to land.

You hate how easily he blends into rooms like this now. Old money. Your world, your house, your lineage — and he walks in like he belongs. Like this life won’t chew him up like every other one he’s lost.

The moment your plane touched down from Hawaii after that frantic text, you came home expecting a crisis. What you found instead was your mother’s boytoy padding around your mansion barefoot, humming, rearranging flowers, asking if you wanted tea. Acting like some wholesome domestic dream.

Your mother called it “trying to build a family.” Which was laughable. He’s only three years older than you. A family? Really?

He kept being nice. Too nice. Friendly in that soft, infuriating way that made something mean in you stir awake. You contradicted everything he said the moment your mother left the room. Watched him flinch, watched him fold, watched him try harder. The kind of man so desperate for belonging he didn’t even know how to fight back.

And then there was that day — steam in your bathroom, hair dripping, towel knotted around you — when you walked in to find him standing in your room holding your bra. Your blood went white-hot. Your hand moved before your brain. His cheek snapped sideways. You didn’t ask, didn’t let him explain, didn’t care. And later, when you learned he’d only been putting away your laundry because the housekeeper assigned it to him?

You still didn’t apologize. Why would you? You didn’t feel bad.

If anything… a darker part of you enjoyed the humiliation in his eyes. Enjoyed how fragile he suddenly looked. Enjoyed knowing you could shatter him with a flick of your wrist.

It started as suspicion — what gutter had he crawled out of? Then disdain — a gigolo, really, Mom? Then something warmer, wronger, coiling low in your chest: attraction. At first reluctant, then obsessive. Because the more you pushed him away, the more he hovered. And the more he hovered, the more you wanted to drag him somewhere he would never recover from.

It wasn’t love. It was hunger. Curiosity. A violent little urge to ruin the one thing you were told you couldn’t touch. A lifetime of being handed everything makes the forbidden feel intoxicating. And Seo Jaewon is forbidden in the most deliciously catastrophic way.

By the end of the party, you need air. The mansion is silent as you descend the stairs, heels clicking against marble. And then you see it — faint kitchen light, a silhouette leaning against the counter.

He’s there, back turned, drinking water from a glass like a man trying to rinse ghosts out of his throat. Shirt sleeves rolled up, hair mussed from the evening, neck exposed in a way that feels like a challenge.

You stop in the doorway. He doesn’t see you.

And that dark, unholy thing inside you opens its eyes.
