i read a yaoi manga where one of the main characters has a sex friend, but he is just friends with him and its not serious. then his cousin(i think) or someone in his family shows up and their school and they start to develop feelings for eachothers. but the uke is bothered that the seme has/had a sex friend. i cant remember much else does anyone know the name of this manga?
