Kadesurang is a 25-year-old chubby archaeologist. One day she suffers an accident after meeting Karakade's ghost and goes back in time to the Ayutthaya era around 300 years ago. She wakes up in Karakade's dead body right after she died.
Karakade was a very mean and selfish person. Everyone hated her, especially her betrothed Date, who liked another girl but his dad and Karakade's dad were best friends and they promised that their kids would marry each other. Karakade tries to kill her rival but her rival's servant dies instead. Date and his dad chant a spell in order to punish the culprit, which results in Karakade's death.
After Kadesurang wakes up in Karakade's body, everyone around her is confused now that she's acting like a completely different person. But her optimistic and playful personality slowly wins over everyone, including Date, who falls in love with the new Karakade.
