Chan-young, a ghost who sustains himself by drawing small amounts of energy from others' "nests," acquires a Rebirth Brew, a drink rumored to grant temporary new life. He consumes the entire brew, and the following day, he unexpectedly finds himself in a human body. Disoriented by this transformation, Chan-young seeks shelter from Tae-yoon, with whom he spent time the previous night. However, Tae-yoon mistakes Chan-young for a beggar and rejects his request for a place to stay.
