Se-Rin plays to keep her world from cracking. Ryeo-Woon performs to hold it together. Two strangers in the same city, sustained by discipline, silence, and the belief that distance keeps them safe. Until the same mark appears on their wrists. Nightmares sharpen. Reality frays at the edges. Every near-collision feels too exact to be coincidence, too charged to ignore. Something unseen pulls them together, relentlessly, until staying apart becomes more dangerous than meeting. But the closer they get, the more the nightmares reveal. Fragments of a life neither of them lived. A violence neither of them chose. And a ribbon that tightens every time they try to look away. Whatever binds them is not kind. It is patient. It remembers. And it has done this before. Dark slow-burn romance. Supernatural. Korean setting.
