The story, without the spoilers.
Park Si-on is a young man with autism and savant syndrome who can see the human body the way other people see a map. Numbers, patterns, and tiny details stay in his head exactly as he saw them, and that gift makes him a brilliant young doctor. It also makes everyday life hard: crowded rooms, sudden noise, and unspoken rules leave him lost. When he joins the paediatric surgery team at a large hospital, almost no one wants him there. Senior surgeon Kim Do-han thinks he is a risk to patients, and the hospital board sees a problem to manage. Only fellow surgeon Cha Yoon-seo looks past the awkward first impression and sees how carefully Si-on studies each child in his care. Every operation becomes a test, not just of his hands, but of whether a hospital built on habit can make room for a different kind of mind. Warm, tense, and often moving, this is a medical drama about talent, prejudice, and the quiet courage of being underestimated.
A little curiosity. A new favourite.
