Hyde, Jekyll, Me

The series is based on Lee Choong-ho's webtoon Dr. Jekyll Is Mr. Hyde, which put a romantic comedy spin on the classic literary character of Jekyll and Hyde.

Hyun Bin took on a triple role in the series, playing the cold chaebol Gu Seo-jin, his gentler alternate personality Robin, and a third personality named Terry.

Author Lee Choong-ho publicly accused the screenwriter of the rival series Kill Me, Heal Me of plagiarizing his webtoon, since both dramas center on a woman falling in love with a man with dissociative identity disorder and aired in the same time slot.

MBC denied the plagiarism accusation, while SBS clarified that Lee Choong-ho's statement reflected only his personal opinion and not the stance of the production team.

A Thai television drama, Song Huajai Nee Puea Tur on Channel 3, was criticized for having a plot too similar to Hyde Jekyll, Me, though its producer denied any plagiarism.

The series received generally negative reviews from critics, particularly criticized for its inconsistent plot, and had low ratings for a prime-time slot.
