6 - salaryman with an unrequited love is mourning the complete loss of his crush when he finds out the guy got married (even though he knew it was impossible because he was criminally straight maybe homophobic) and asks a kid to spend the night with him for money because he looks exactly like his unrequited love when he was in highschool. The kid agrees, thinking that it'd be fun & knowing there'd be money in it for him. They sleep together and make an agreement to see each other again under the premise of pretending to be his lost love. Things work out great... Until the kid realizes hes in love with the salary man and loathes the idea that he isn't seen as himself while the salary man cant bring himself to see the kid because hes in love with him and they have a decent age gap, as well as the fact that they both don't like the idea of exchanging money to be in each others company anymore. It all comes to a head in the middle of the street and they get together officially.
