Cynical, sincere, unapologetic, heavily traumatized and with a record of three failed suicide attempts, the youngest daughter of the wealthy Kim lineage is nothing but trouble. Kyung Soo meets her when he accompanies his friend from university Kai to his house for summer vacation , and everything about her seems to captivate him. Still he is yet to know the trouble that comes with the beautiful Kim Eun Hee, as not everything is what it seems, and there is not such a thing as a family without secrets.
