Taecyeon and Junho are both unhappy people. Taec – although he's the director of a successful company and lives 'the good life' that would usually be every man's dream – wants nothing more than to break free of the chains of the corporate world and live the life of freedom of self expression that he's always dreamt of . . . while Junho struggles with a difficult relationship that most would call 'bad', a family that's always discouraged his goal of being a singer/songwriter, and just utter emptiness in his life. After a late night affair in their office place, the two co-workers make a pact to help brighten each other's days and bring that missing 'spark' back into their lives . . . but can they resist falling for one another along the way?
