Leading the cast is Kwon Oh-bok (Kim So-eun - in her first ever leading role in a drama series), a talented 19-year-old girl who aspires to be a recognized illustrator and allows herself very little in terms of being swayed by any trials or tribulations.
As the drama continues, Oh-bok gets to know Dae-han's younger brother, Jang Min-guk (Lee Hyun-jin), a drifter, upon saving his life when she thought he was trying to commit suicide.
