The only way to escape his punishment is to win over a human’s heart, which won’t be easy…especially when the human he sets his eyes on is sweet-natured prince Lee Nok. Will Jae-shin win over the prince? Or will Jae-shin be the one who is won over?

A thoughtless finger slip leads Joe to snap a picture of Yeongwoo (Ian) smoking on his balcony - and thus, their fates begin to intertwine. Joe can't stop fantasizing about the tall, handsome stranger on the balcony, and and he grabs any chance to get to know him better. Unfortunately, he doesn't realize that Yeongwoo does the dirty work for one of the region's largest, most unsavory gangs... and is the ""lover"" of one of their most powerful people. A violent struggle for succession within the gang drags Yeongwoo deeper into this hellish cycle, making him the target of both detectives and other gang members, and it only makes him crave Joe's bright innocence even more. Although they undeniably yearn for each other, Yeongwoo's darkness might be enough to consume them both. Will Joe be able to free Yeongwoo from despair, or will he succumb to the violence and corruption himself?
