Go Woon-ha, who constantly seeks stimulation but has dulled pain receptors and rarely feels anything, experiences pleasure for the first time in his life after spending a night with his partner’s younger brother, Cha Gyu-won.

However, his partner in that encounter turns out to be the worst kind of person in Woon-ha’s book younger, and even a virgin who made a vow of chastity.

“So, you’re saying you’d have sex without getting married”
“Hey, you were the one eating me out back there don’t act like I’m the only one who did something wrong.… What, were you planning to marry me or something”
“Can you even do that We’re both men.”

A younger guy, a virgin, and on top of that, one who believes in premarital purity and fantasizes about marrying his first love.
Seriously the absolute worst.
He really shouldn’t have slept with him.

“It’s fine. If it was from behind, it doesn’t count.”

While Woon-ha thinks that way and brushes it off, Cha Gyu-won, on the other hand, makes a life-changing resolution in that very moment.
