The drama aims to provide viewers with both hope and a refreshing breath of air, telling the story of a girl who discovers she has a terminal illness, and decides to live by saying what she wants. This role will be played by Go Ah Sung, while opposite her will be Ha Suk Jin, a cold upper manager; Lee Dong Hwi, a romantic office worker; and INFINITE's Hoya, a smart but introverted office worker. 

Actors and actress such as Sunhwa, Oh Dae Hwan, and more also plan on adding charm to this office-drama, set to air after currently airing 'Missing 9', some time this March.
