Ca Dao is a woman who feels she is cursed with bad luck. She has always dreamed of becoming a famous singer, but her career has never taken off, so she is stuck in a dead-end office job.
Things go from bad to worse for her when she misses a key meeting and her long-suffering supervisor wants to fire her.
The company’s boss decides to give her one last chance to redeemherself or face the sack – she must recruit vain and egotistical K-pop star Chan Y to feature in the company’s marketing campaign.
She attempts to win over Chan Y, but he is not interested in her pleas.
But the next morning, something remarkable has happened – the duo has undergone a body swap! The “new” Chan Y is hopelessly unaware of how to act like a pop star, while the “new” Ca Dao finds life as an office worker – and a woman – exceptionally difficult!
The pair begrudgingly agrees to help each other out…until they slowly start developing feelings of mutual respect.
