The tangled fates of the heiress of a cosmetics company and a woman who had to achieve everything on her own.

As a child, Park Shi On was sent to a specialized care center, where he discovered genius capacities for his autism. Coupled with an exceptional memory and keen spatial skills, the young savant eventually entered pediatric residency, where he developed into a promising surgeon. However, his mental and emotional development seems to have stopped at 10-years-old, which makes for incredible conflicts in and out of the O.R., especially with the hotheaded surgeon Kim Do Han.
