I have a beautiful master with a strange quirk. She raised me as a girl from the time I was little.
As a result, I've maxed out every skill associated with being a young lady.
At last, when I turned sixteen, I was allowed to go down the mountain and gain experience.
I'd had enough of wearing women's clothes, so I secretly changed back into men's clothes. I even had a girl I liked.
But I had a rival in love: the senior brother of the girl I liked.
He was handsome, suave, gifted, and older than me.
Then one day, an accident happened, and I wound up carrying my rival's child. To my dismay, I discovered that the techniques my beautiful master taught me didn't just make me prettier: they had changed my sex too!
