Goun-ha, who seeks stimulation but has a dull sense of pain and can hardly feel it, experiences pleasure for the first time in her life while sleeping with her partner's younger brother, Cha Gyu-won. However, the other person was a younger man, whom Goun-ha considered the worst, and a virgin who had even pledged chastity. "Then you're having sex without getting married?" "No, you can't suck my back like that and act like it's my fault. ... Were you thinking of marrying me?" "Can you? You're a man?" A younger man, a virgin, and a man who fantasizes about getting married on his first date. He's really the worst. "I screwed you wrong. It's okay, what I did behind your back is invalid." Separately from Goun-ha who was thinking such things, Cha Gyu-won ended up making a certain pledge that he would stake his life on.
