Kwon Hyeonseong, a genius painter hit by a slump, is betrayed by the corporation that sponsored him. Forced to halt his secret investigation into his mother's plagiarism case, he now faces the crisis of losing both his studio and his home. To make matters worse, the person who usurped his position turns out to be his ex-boyfriend, who caused him deep pain in the past.

In the midst of this turbulent situation, three men with their own motives approach Hyeonseong:

Yoo Hee: The bold younger man who demands Hyeonseong take responsibility for their one-night stand.

Yuri: Yoo Hee's older brother, who approaches Hyeonseong to gain the upper hand in a succession battle.

Lee Haein: The relentless ex-boyfriend who will stop at nothing to reclaim Hyeonseong.

Caught between the three men, Hyeonseong struggles, unable to define any of his relationships.
