A Villainess in Disguise

A girl who loves to disguise herself into another person.
Nobody knows who she really is.
Every time she goes in public, she wears her different self, she portrays many masks of a person's identities. Copying, acting, just to erase her true self.
Even when the time comes, her life ends because of a person who stabs her stomach.
That breaks her heart when she saw the person who stabbed her, that person who is dearest to her.
And her heart is torn into pieces when that person doesn't regret it at all, in fact, there is no emotion that will be seen in her beautiful face, and then she walked without turning back to her until she dies.

But that's not the end of her story when she was given a chance to live again. But she was confused because of her body. She was confused if she were just given a chance to live with her own body? Or she was given a chance to live in other body with the same body as her?

That will be the story of A Villainess in disguised.
