Plot
When a gangster (kkangpae) pretends to be a doctor in order to hide from the mob he left behind, he doesn't realize that this innocent deception will set him on the path towards love and redemption. Kang Dal-go, a mid-level member of a Busan gang, gets kicked out of the gang after being investigated by the police and is forced to flee for his life. Hiding out in Seoul, he gets hired as a doctor at a nearby hospital, where he quickly clashes with Kim Yoo-na, a dedicated and outspoken doctor. Gradually, however, the former gang member and the beautiful physician begin to fall in love in the midst of their clashes, to the dismay of prosecutor Seok Hee-jung, who is also pursuing Yoo-na. Dal-go may want to start a new life, but it's uncertain if his past will allow him to do so, and what Yoo-na's reaction will be once she discovers the truth.
