After a tragic accident, Sangwon clings to memories of Anxin, the friend and love he lost. Years later, he sees Anxin again-but the boy doesn't recognize him. Even without memory, their bond endures, proving that some loves can survive beyond life itself.

They say brothers are meant to fight, to laugh, to protect each other, to share the same roof and the same life. And for as long as I can remember, that's what Anxin has been to me-my brother. But somewhere along the way, something changed. The late-night talks, the way his smile lingers in my head, the way my chest tightens when he's near. It's wrong. It's forbidden. It's the one rule I can never break. Because no matter how much I want him... he's my brother. Or at least, that's what I've always believed.

They can't stand each other. Literally. Lee Sangwon is sharp, meticulous, and thrives on control. Zhou Anxin is impulsive, unpredictable, and loves breaking every rule Sangwon lives by. When they meet at the same company, sparks fly-and not the good kind. Every meeting is a battlefield. Every interaction, a clash of egos. Anxin rolls his eyes at everything Sangwon says. Sangwon finds Anxin infuriating in every possible way. Yet, inexplicably, every accidental touch, every late-night collaboration, every heated argument ignites something neither wants to admit. Hate feels easy. Desire? Impossible to ignore. As their rivalry intensifies, so does the magnetic pull between them. They hate it. They hate each other. But they hate being apart even more. And soon, the line between hate and love becomes blurred... dangerously blurred.
