Kim Young Soo, a department store worker, tragically dies in an accident. In the afterlife, he pleads for a chance to return to resolve the misunderstandings surrounding his death and console his grieving wife, Shin Da Hye. Alongside him is Han Gi Tak, a rugged chef with his own unresolved issues from his past life. Their request is granted, but they must return in new, unfamiliar bodies and are forbidden from revealing their true identities. Young Soo's reincarnation shares the appearance of the department store's new chief, adding complexity to their mission, while Gi Tak returns in a woman's body. With limited time, they must work tirelessly against all odds to ensure the well-being of their loved ones in their absence.
