Synopsis
All I did was to live up to my calling. TRS is a nursing robot customized for each patient: all the robots look just like each patients’ family member. Jung-in had hired it to take care of her mother who's been in coma for several years. However, her cumbersome days are slowly strangling her. Seeing Jung-in suffering from depression puts her TRS in a dilemma because Jung-in is also registered in the caring service. The perfectly programmed machine starts to stumble.
