## Synopsis

The human body is capable of all sorts of things to survive difficult situations. Cha Do-hyun (Ji Sung) is a third-generation business heir who developed dissociative identity disorder (previously known as multiple personality disorder) in the aftermath of several life-threatening traumatic events. He tries to regain control over his life with the help of Oh Ri-jin (Hwang Jung-eum), a beautiful first-year psychiatric resident who helps him secretly. But Ri-jin's twin brother, Oh Ri-on (Park Seo-joon), is a writer who is determined to uncover the unscrupulous lives of the rich and starts following Do-hyun around. Can Do-hyun take control over his condition before one of his seven identities takes control of him instead?

## Cast
### Main

** Lee Do-hyun as child Cha Do-hyun (Cha Joon-young)
    A wealthy businessman with a warmhearted personality who loves to help others. He is the main personality of the body. However, after realizing that he suffers from dissociative identity disorder 11 years ago, he has been desperately trying to hide this fact from his families and friends. In Episode 17, it was revealed that Cha Joon-young is his real name. He has six other identities:
   * Shin Se-gi: A vehement young man with a devil-may-care demeanor who appears when Cha Do-hyun experiences violence. He may be violent, but he never hurts children and women. Se-gi endures all of Do-hyun's pain as he is the only identity to have all of Do-hyun's memories. His first love is Oh Ri-jin.
   * Ferry Park: A 40-year-old man with an affinity for fishing and building bombs. He appears when Cha Do-hyun reminisces the sweetside of his father before they came back into the mansion. The name "Ferry Park" came from the promise Do-hyun (Joon-young) made to his father, which is to buy a boat named Ferry Park Boat for him. He speaks with a Jeolla dialect.
