I read this manga months ago, but i forgot the name. So there's someone out at this all girls school who is molesting innocent girls. The main girl finds out that its actually a boy dressed as a girl who was traumatized by a woman in his family when he was younger.

Something like that.. i know my description is pretty vague. Do any of you guys know what it is? Thanks in advance!

could it be Taiken second story -Tengoku No Tsuki

That's it! Thank you so much!
