Xu Yan is the son of a wealthy country bumpkin.
He lost his mother when he was little, but thanks to his clever mind, he got into university at sixteen. During university military training, he hit a girl in the back of the head while target shooting in the woods. When she woke up, she insisted she was from more than a decade ago, had just given birth, and that her husband was called Xu Pingming and her baby was called Xu Yan.
Xu Yan: Heh, what a coincidence. My dad's called Xu Pingming too.
I'll write when I think of it, and update when I've finished. Probably once a year or so _(:з"∠)_
