When Jae-hyun returns home after five years, he expects silence, space—and maybe a chance to reset his life.
What he doesn’t expect is his father’s new wife: Yuna—young, confident, effortlessly seductive. She lives like the house is hers. It is.
But Yuna isn’t alone.
Her close-knit circle of friends—bold, curious, and far too interested—begin showing up, each one testing his limits in their own way.
They laugh, drink, flirt... and cross boundaries he didn’t know existed.
He was supposed to stay low, finish school, and keep his distance.
But now, every night feels like a dare.
And Yuna? She’s always watching.
