You and I

Ca Dao (Hari Won) 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 redeem herself or face the sack - she must recruit vain and egotistical K-pop star Chan Y (Jung-min Park) 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.
