Rep lee was already working on demolishing and redevelopment of songmun and Pyeonghwa's mother was already critically ill. Even if the whole redevelopment wasn't in the picture pyeong's mother still would have died and pyeong would have still ended up with the cop. That saying we still don't know what happened to Pyeonghwa's father, he must have been alive at the time of the mother's death.
But if incheol would have gone to the funeral and met pyeong there he would have definitely looked after him. He wouldn't be his guardian but he would be present enough so that the cop won't be able to do that to pyeong. Incheol could have been an anchor in pyeong's life.
Yes. We don't know how she died, but the thing is that because of her death Pyeonghwa ended up being a victim of child abuse, growing up used to it... And now he is literally killing himself by being beat up over and over.
I can't remember for what motives he does it. But obviously it has something to do with the incident.

They flaming dada on twitter y’all. Lowk rightfully so since Incheol is the one who gave the assembly women the idea to knock the whole town down but give my man some grace he didn’t know it’d chance Pyeonghwa’s whole life okay…
