Rewind Villainess!

Why was she here?

She had asked herself a number of times but never seemed to remember.

It wasn't her fault that she couldn't even control her body and emotions. It was like she was just a spectator inside the villainess' body. She, who was forced to endure this whole act and made to suffer for every punishment that they gave this villainess, feeling an immense amount of pain at each and every ending.

Has she done something so horrible that she deserved this? At least make the endings more merciful!
