Intro. You wake up with a girl by your side, you realize that she has no emotions and seems to obey your wishes, after a while you realize that when you sleep you wake up in her body and you can only go to the other body if you sleep again But there's one thing: your original body is having problems and you can't use it much. Your old body now feels very sleepy, now you'll have to get used to the new body and gender
