Synopsis
Gu Seo-jin (Hyun Bin), is a third-generation chaebol who runs the theme park Wonder Land. He seemingly has everything looks, brains, and fortune. He is also in line to become the next CEO of Wonder Group, the conglomerate his family owns, though his cousin Ryu Seung-yeon (Han Sang-jin), who oversees Wonder Hotel is his rival for the position. But Seo-jin has dissociative identity disorder. Whenever his heart rate exceeds 150, another personality emerges, and unlike Seo-jin s usual cold, cynical and ruthless self, Robin is kind, gentle and has a savior complex. This split personality began 15 years ago, and Seo-jin s doctor Kang Hee-ae believes that Robin is a manifestation of his guilt regarding a traumatic incident then. Because of this, Seo-jin avoids anything that might cause him to have a strong physical or emotional reaction which could trigger Robin s reappearance, even if that means shutting himself away from the world and eschewing any meaningful relationships.
