Gu Seo Jin (Hyun Bin), the director of theme park Wonder Land, is also a third-generation member of the family that owns Wonder Group, making him one of the contenders to be the next CEO. However, for the past 15 years, Seo Jin has privately dealt with dissociative identity disorder, avoiding any activities that might trigger the appearance of his alter, Robin, whose kind and gentle personality contrasts with Seo Jin’s cynical, ruthless ways. This grows increasingly difficult when Jang Ha Na (Han Ji Min), the next-generation director of the circus show at Wonder Land, returns with plans to revamp the failing show. Seo Jin had planned to cancel the show due to poor margins, but Ha Na refuses to back down, leading to Robin’s personality emerging more frequently. As the stakes grow higher, Seo Jin, Ha Na, and Robin’s relationship to each other continues to evolve in ways none of them expected.
