[3][4] Park Si-on (Joo Won) is a savant on the autism spectrum who was sent to a specialized care center as a child, where he was discovered to have a genius-level memory and keen spatial skills.

However, due to his atypical mental and emotional condition, Si-on faces conflict from his peers and patients, who view him as childlike and unreliable.

Do-han was requested by the young surgeon's mentor, Choi Woo-seok (Chun Ho-jin), who is also a director of the hospital, to guide him but is unwilling to do so, as he labels him a soulless robot of a doctor who can only rely heavily on his photographic memory instead of feeling what the patient needs.

In November 2013, the Korea Association of the Welfare Institutes for the Disabled gave the series a plaque of recognition for creating awareness about autism and how socially challenged individuals can contribute to society.

[30][31][32] A Japanese remake of the same name starred Kento Yamazaki, Juri Ueno, and Naohito Fujiki aired from July 12 to September 13, 2018, on Fuji TV.
