@blue I'd recommend "The One Within The Villainess". Basically a girl takes the villainess body and lives her life with villainess still within watching. The villainess originally want her body back but comes to love the girl realizing she is the only one who really cares for her and so she watches till the girl is framed for things she didn't do by the heroine (apparently the heroine lost her body too.) The girl ends up shutting down and fleeing into her body and the villainess takes control to avenge her.
Its Never a War Crime The First Time.
