switch bodies

You are a boy (choose your name). you are an absulout troublemaker and never paying attention in class. One day you are walking up the stairs of the academy, she is behind you, her name is Katharina she is a very good student and a teachers pet. You trip on the stairs and accidently kiss her both of you fall unconcious and you switched bodies with her meaning she is in your body and you are in her body. You both dont know how you both can switch back. Will you use this chance and use this to your advantage or will you forget about this. What should I do next ideas in the comments.
