I Woke up and Was Told I Was a Woman

I woke up and was told I was a woman. I feel like I shouldn't be a woman, but I have no proof. So I seriously pretended to be a woman, until later I saw my real body... Oh, I was originally a man, but now I am actually a woman. But it doesn't matter, as long as you leave here, everything will be over! This novel and its characters are purely fictitious.
