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...?
