Kwon JiYong is best friends with the councilor, Dong YongBae at his old university. However, having studied music, JiYong's career isn't quite going as planned. He is deperate for work and slowly falling behind on his bills. YongBae thinks that he might do well at mentoring students at the university that YongBae thinks need help out side of sessions. Needing the money, and not fussing over where it comes from, JiYong finds himself mentoring a first year student. 

Hana knows she's not depressed. Just over worked and tired. But her 'pschologist' thinks that her condition will worsen over time. He assigns a mentor to her, a man, older than her by seven years. She thinks that it is rediculous, being watched over like some sort of pet. But as time passes and her mentor tries to get closer, how will she end up feeling towards Kwon JiYong.
