The loan shark was the uke right? And seme is blonde?
thanks sky that was totally it! :)
it was about this loan shark who was making this dude have sex with him because he wasn't paying enough I think? he starts falling in love with him and I think there was a sex scene in a car? the guy that owes him money lives with his grandmother and little sister maybe? I don't exactly remember but I really want to find it.
