Na Bong-sun, a timid assistant chef who can communicate with ghosts, has a crush on star chef Kang Sun-woo. Meanwhile, mysterious cases of hypothermia start taking place.

Possessed by Soon-ae, the ghost of a lustful virgin, Bong-sun becomes confidently libidinous. Meanwhile, Sun-woo decides to participate in a cooking competition show but faces difficulty from the very beginning.

Memories come flooding back to Soon-ae, who is trapped in Bong-sun's body. Meanwhile, things start to go missing at the restaurant, and the crew members are shocked when they learn the truth.

With no place to stay, Bong-sun tries to sneak into Sun-woo's restaurant to stay for a night, but Sun-woo catches her and kicks her out. While at the broadcasting station with Sun-woo, Bong-sun discovers Sun-woo's weakness and uses it against him to get herself a place to stay.

Bong-sun is finally separated from Soon-ae's ghost but gets scared by the strange things happening to her. Meanwhile, the day of the second cooking competition arrives, and Bong-sun faces difficulty as she is back to her real self.

Soon-ae appears before Bong-sun and asks her to help her father, but Bong-sun does her best to ignore her. The cooking competition ends successfully, and Sun-woo offers Bong-sun cooking lessons. Later on, the two unexpectedly go on their first date.
