A straight-laced student gets caught up in the kind and overwhelming love of an older, cunning student. University student Makoto is currently fighting with his boyfriend, Ryohei. They did it all the time when they first started dating, but Ryohei suddenly won't even touch him. One night he went out with Ryohei's friend, Yuki, when Makoto woke up after a night of drinking--he getting spooned by Yuki! His sweet words resonated with his frustrated, pent-up body... "Would you like me to help you relieve some of your build-up...?"

"Jin Yu-an is a shy, sweet-faced sub who’s never actually tried any real SM play. He’s never had a partner or a lover—mostly because he’s way too busy, kind of a scaredy-cat, and hasn’t found anyone who fits his taste. One day, while browsing a BDSM app, he stumbles upon a profile that makes his heart race… only to realize the guy hasn’t logged in for years. Still, hoping against hope, Yuan starts sending him cheerful messages. And then—a reply. [You got a death wish?] [Can’t you see my age?] Oops. He missed the guy’s age. And the terrifying attitude in the response? Yikes. But somehow, Yuan gets stubborn and insists on meeting him. The guy is exactly his type—intense gaze, scary tattoos, and an aura that screams danger. BDSM? More like organ theft?? Still… should he give this scary-sexy dom a shot?"
