Beneath the bravado and strength is a fragile soul. She has lived in the shadow of her mother since she was a child and has been psychologically damaged. All she does is to let the people she likes know that she is better than her mother. But fate didn't seem to favor her. She died due to careless practice before she could implement her plan. A similarly unhappy soul took possession of her body. What happened to this soul might really be what she wanted to do but didn't do, but not entirely. A new soul tells a new story in a body that didn't belong to her. After she got this new body, she also had the idea of starting over again, but her life was inseparable from the influence left by her original self. After going around and around, she realized that they were the same person, so why bother to separate you and me.
