Let me introduce my sex friend. Jun-chan is a 22-year-old female college student who is very happy because she has a good relationship with her boyfriend and they have a lot of sex. But she says that's not enough for her. I think she's greedy, but maybe that's what young people are like these days. I hope to continue being sex friends with Jun-chan, who is going to become an office lady at a temporary staffing agency, even after she finds employment.
