Horror writer Seol Gongchan finds himself in a mysterious romance with his neighbor from downstairs.
As a horror novelist, Gongchan has a vivid imagination that often blurs the lines between reality and fiction. He dismisses the idea of ghosts as mere figments of his creative mind, until he meets Youngmin. Youngmin is tormented by the haunting spirits from Gongchan's novels, and suddenly, the boundary between the supernatural and the mundane begins to disintegrate.
As Gongchan's feelings for Youngmin deepen, he can't help but wonder if his racing heart is due to their growing connection or the sinister ghost lurking in the shadows. Excitement and terror collide in this chilling love affair.
