The story, without the spoilers.
Cha Do-hyun is the heir to a powerful family, but a childhood trauma has split his mind into seven distinct personalities, each with its own name, voice and way of seeing the world. One is violent, one is a teenage girl, one is a quiet artist, and each appears when Do-hyun is under stress. Oh Ri-jin is a first-year psychiatry resident who becomes his secret doctor, determined to help him heal without exposing his condition. Kill Me, Heal Me is an extraordinary showcase for Ji Sung, who switches between personalities so completely that you forget you are watching one actor. It is funny, romantic and genuinely moving about trauma, memory and what it means to be whole. The mystery of Do-hyun's childhood unfolds slowly, and some twists lean on melodrama, but the performances and the emotional honesty carry it. Hwang Jung-eum is warm and brave as Ri-jin, and Park Seo-jun shines as her protective twin brother.
A little curiosity. A new favourite.
