In a near-future Korea where cryonic sleep has become a commercial option, people can pause their lives for decades—but nobody escapes the consequences of that choice. Gyu-seon, a technician at a cryonics clinic, distrusts people who freeze themselves, unaware that his fiancée Ga-eun has her own connection to the frozen. Journalist Eun-tae pursues a suppressed investigation, while patient B-17903 prepares to awaken after fifty years spent waiting for a woman from a prophetic dream. Their apparently unrelated lives gradually converge across altered ages, buried secrets, and choices made decades apart. Using cryonics as a one-way time machine, the novel explores love, escape, selfishness, identity, responsibility, and whether starting again can ever erase the life left behind.
