Yuri, one of the schools most handsome guys, and Jaerim, one of the schools ugliest, collide!...or don they...Can understand whats going on between these two! Its Out of Control!! Original Webtoon Official English Translation

As the son of King Yeom-ra of the underworld, Jae-shin has lived a hedonistic life full of ever-changing bed partners and condescension towards humans. One day, however, he crosses a line and is given a rather unusual punishment: by day, he becomes a powerless puppy, and by night, he becomes a human. 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?

Sangnam has one dating principle he can't give up "sleep first, date later"! He won't even start with someone who isn't sexually compatible, but finding someone he likes isn't easy. Then Sangnam notices his junior Daol, who clearly can't hide that he likes him. At first, Daol's huge build and gloomy appearance were annoying, but when he saw his face... this guy might actually work? Though I'd have to change him to suit my taste. When Sangnam proposes that he'd consider dating if Daol transforms his body to Sangnam's satisfaction, Daol nervously accepts. But Daol has a preference he can't tell others about...?
