i know the struggle
you said too:
I Dont have the game freshly played. but i remember the short dressing without underwear and that she was forced. I do think that a good character evolution would be having a break time (some kind of short holidays period of few days) where she can access to different dressing and she discovers, to her surprise, that she enjoys the lack of underwear and the very short dressing, so she begins to do it on purpose and to experiment by herself this way of acting in public places. it would make her character to evolve a bit, maybe as a way of coping and accepting the situations she has been forced to. some of her enemies, at some point, would find out that she really is a bit of a pervert, so the situations could scalate a bit thanks to that.
just an idea. i dont know if it will be useful or not.
also, to keep the tension, i think that she deserves to take off some of her enemies. as a way to show that she is able to, at some point, overcome and obtain a tiny victory. that would give some hope and would reasure her in her path.
