Ko Woon-ha craves intense stimulation but has such a dull sense of pain that he rarely feels anything at all—until he ends up in bed with Cha Gyu-won, his partner’s younger brother, and experiences pleasure for the first time in his life. But the problem is… the guy is everything Woon-ha hates: younger, a virgin, and someone who even made a vow of abstinence.

“So you want to have sex without getting married?”

“Hey, you can’t act like I’m the only one who did something wrong after you sucked me off like that. …Wait, were you planning on marrying me?”

“Is that even possible? We’re both men.”

Younger, a virgin, and on top of that—a premarital-purity type with a fantasy about his first relationship leading straight to marriage. Seriously the worst. Woon-ha really screwed the wrong guy.

“It’s fine. Anal doesn’t count.”

While Woon-ha comforts himself with those thoughts, Cha Gyu-won, on the other hand, makes a decision—one serious enough to stake his entire life on.
