The drama draws a love story between two co-workers at an insurance company, with Kim Ji Hoon playing the company's whip-smart lawyer. Because he carries the hurt of having been abandoned by his birth mother, he doesn't easily open his heart to others. Jin Pal Kang (Choi Jung Won) is a 25-year-old employee of the company who becomes responsible for her five younger adopted siblings after her parents meet with sudden deaths.
