However, the girl lies about her job in her profile, saying she's in the fashion industry when she is in fact working as a prostitute. Eventually she reveals the truth to him, asking him: “Even if I date you, I won't quit my job. Can you still be with me?”. He decides to stay with her but this decision is the start of soul-eating inner turmoil of dealing with the knowledge that his beloved girlfriend is giving her body to other men.
