Based on Lee Choong-ho's webtoon Dr. Jekyll Is Mr. Hyde, this 20-episode 2015 television series gave a rom-com twist to the popular literary character. Hyun Bin plays two characters: Gu Seo-jin, a third-generation chaebol who runs the theme park Wonder Land who seems to have everything from dazzling looks to intelligence and fortune; and Robin, a kind and gentle version of himself who emerges whenever his heart rate exceeds 150. Gu Seo-jin has a dissociative identity disorder. 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. Jang Ha-na (Han Ji-min), the series' female lead, has just returned to Korea after spending several years in the United States with Cirque du Soleil. The three characters get involved in a suspenseful yet heartwarming love triangle.
In the same year, the show got entangled in a controversy after an article in Korea JoongAng Daily said that the author Lee Choong-ho, who in 2011 wrote the webtoon Hyde Jekyll, Me where the series was adapted from, alleged on his Twitter account that the screenwriter of Kill Me, Heal Me plagiarised his work. MBC denied the plagiarism accusation, while SBS clarified that Lee's statement was his personal opinion and did not reflect the stance of the whole production team.
Hyde Jekyll, Me and Kill Me, Heal Me are both available on Netflix.
