God I forgot the name but
Uke I think is in the closet country boy that moved to the city to study, seme that's like his neighbour is a hot playboy.
I think it started like the seme had a party with 2 friends(boy and girl) and the hetro's started to makelove so the seme and uke moved to the ukes place, and seme found out uke is gay and they started to have sex.
Not a long storyy like 6 chapters
