I would like some suggestions on mangas where the female lead pretends to be a boy for whatever reason. No hentai or yaoi please! I would also prefer it to not be a shounen manga... It would also be interesting if the girl had some sort of gender disorder that makes her believe that she is a boy! ROMANCE PLEASE!
On a lighter note, [m]PrincessKnight[/m]. She is a girl who has both a girl's heart and a boy's heart. She knows she is a girl, but when her girl's heart is magically removed, she thinks she is a boy. Not in scanlation, but available in two English volumes.
But I'd suggest you to try advanced search with Gender Bender and Romance checked and maybe some additional categories such as Androgynous Protagonist or Crossdressing depending on what exactly you want.
