been looking for this manga

it was a BL where Mei-kun (I forgot if he was the seme or uke) is a crossdresser. I think he was picked up by a geezer, (I dunno the name ><) and in the extra, mei-kun's collection said that he crossdresses differently when going for different people, like dressing as a university student when going for students to salarymen, dressing as a gyaru when going for flashy men and an office worker she going for old men-
