just had this idea that i'll definitely never put on paper because i have no time π₯²
wangxian have a biological child post canon, at cloud recesses, and the kid grows up with wwx being the strict partner and not in the funny kind of way but actually very strict, especially with manners. wwx is always scolding his child because they dirtied their clothes, played with other children in public, laughed a bit too loud, cried too much, and the kid kinda ended up running to lwj a lot because of that
when the kid grows up he realizes a bit too late why his father was like that and why his other father never said anything and only looked sad - and he only realized that /that/ expression on his face wasn't annoyance or exasperating as they thought when they were a child. wwx was deeply afraid that his child would be treated either poorly or like him in the sect just because they are the yllz's child. there's a rule about interacting with him, will they extend it to his child? will they click their tongues and say that's expected from the spawn of that man when the child does something as simple as being happy? will they? will it? what if-?
so instead of being an angst emo teen who cries that their parents don't understand them, they turn their anger at their clan and sect, and later at the cultivation world when they are told by their Yuan-gege about the story of yllz before and after his death and then confronts lwj about it to get more details and ends up crying on his father's lap asking for forgiveness for all the tantrums, confused anger and unsolicited snaps all these years but wwx cries back and instead of forgiving his child he asks to be forgiven himself because it wasn't fair, he wasn't a good parent
