Kim Joo-Won is a privileged department store CEO with a superiority complex and a meticulously curated life. Gil Ra-Im is a fiercely independent stuntwoman used to being overlooked. When Joo-Won mistakes Ra-Im for a famous actress, their worlds collide in an awkward first encounter that leaves him inexplicably drawn to her. Despite every logical reason to walk away, he begins pursuing her with a mix of arrogance, confusion, and curiosity. Ra-Im, on the other hand, knows better than to get involved with someone like Joo-Won, but resisting him isn't as easy as she'd like to believe. Their unlikely relationship is further complicated by Oska, a has-been pop star and Joo-Won’s troublemaking cousin, along with Yoon-Seul, a coldly ambitious director entangled with both men. A trip to Jeju Island pulls them all together, where a chance encounter at a strange mountain-side restaurant takes the story in an unexpected direction. After drinking a mysterious homemade wine, Joo-Won and Ra-Im wake up to find their souls have switched bodies! Now forced to live each other’s lives, they must also face their own feelings—more intimately than either ever expected.
