Sang-Nam has one unshakable belief when it comes to love: the principle of "self-satisfaction above all"! He never even starts anything with someone who's not compatible with him in bed. But finding someone who ticks all the boxes? Easier said than done. That's when he notices Da-Ol, a junior who clearly can't hide how much he likes Sang-Nam. At first, Da-Ol's bulky frame and gloomy vibe are a turn-off—but then Sang-Nam gets a look at his face... and thinks, This one might just work. He'll need some tweaking to fit Sang-Nam's tastes, but hey, potential is potential. So Sang-Nam makes an offer: if Da-Ol changes his body into something more to his liking, then maybe—just maybe—he'll consider dating him. With a nervous heart, Da-Ol accepts. But little does Sang-Nam know...

Da-Ol has a secret preference he's never told anyone. And it's about to change everything.
