I think it's "dirty high" or "the dirtiest high"?? But I'm not sure.

Maybe not this, because what I know in this story is that Seme is the writer and Uke is the one who cleans his apartment.
All I remember is: bl where uke lives alone in a filthy apartment and seme goes to clean it. Uke is a writer(?) And there's another guy who tries to control him. (I think the bad seme is blonde but I could be wrong) I read it more than once but I never saved it ヽ(`Д´)ﾉ
