Prat is a modest bank employee who lives simply, saves carefully, and dreams of marrying his longtime girlfriend, Chachri—despite her wealthy family looking down on him for being poor. When he proposes, her family reacts with open disdain.

During an argument, Prat accidentally hits his head and wakes up with a completely different personality. Now bold and charming, he confidently hosts a dinner with Chachri’s family and wins them over. But the next morning, Prat hears a strange voice in his room—belonging to a ghost.

The ghost, Thong Kru, was a flirtatious nobleman in his past life and now seeks to earn merit to reach heaven. He possesses Prat’s body to help him win Chachri back. But can Prat keep up with Thong Kru’s wild ways—and will he truly win the heart of the woman he loves?
