Not exactly, he was taken in by Jiang FengMian because of his close friendship with WWX's parents. They treat each other like family (minus Lady Yu towards WWX)
If you noticed JFM's bias towards WWX, it might have something to do with WWX's mother
Oh, alright, but are his parents still alive?
No
Nop, they died during a night hunt, leaving Wei Ying alone. He lived some years in the streets in Yiling, that's where Jiang FengMiang found him after searching for him for some times (you want some angst ? His fear of dogs came from that time because he got bitten by dogs and when JFM found him he barelly remembered his own name). He was 9 or 10 yo when Jiang FengMiang took him in.
Thank you all so much, since I'm an manhwa only reader I get sometime confused about the setting, and I have a really hard time remembering the names, especially in chinese and corean, thus being more confused (￣∇￣")
Is he adopted by the purple family?
