You were not a perfect person in life, but also in your studies as a student, one day you offended a girl who lost her sister, telling her that she died, well, let her sleep. After this, she got offended at you and decided to take revenge... The next day she kidnaps you, she does something surgical with you, which is why you passed out. You came to and saw that you were in someone else's body, but your head was in this body.

"Look!!! Now you are my sister, the one you laughed at, isn't it cute!?"

She pulled out a compact mirror where you look at yourself, in a girl's body with your head and also feminized, in a red turtleneck sweater, with a brown medium pleated skirt, on your feet black knee-high boots with a zipper and on your neck a pendant with an image of your kidnapper and on your shoulder a small white handbag.
