Manga with 3-way situationship

I read a manga abt 10yrs ago where the main lead was a pretty girl who were labeled a tomboy wear pants at school but secretly she wear skirts after school and gets her thrill through that. There was a boy who was famous at their school coz he's a heartthrob but after school, he crossdress as a fetish. Then there was another girl in their school who wears sailor uniform after school to look like a middle schooler and sell herself to old men who got fetish. The FL like the ML but ML likes the girl who wear sailor uniform and think FL was a guy and the sailor girl likes the FL coz she's kind and innocent. This got a lot of problematic elements, its not just a typical school love story. The title is something like "uniforms people wear before 19" but can't find it. If you are familiar pls help.
