Guys crazy thought but what if heo(teach) killed his own dad? Like. I feel like when he thinks back to his fuzzy memories it looks a bit like someone's above him that doesn't look to much like guwon. But we have seen in past chapters that that heo(teach) is actually capable of fighting and flexible and does things in a blurred haze. So what if something happened that causes him to black out and kill his father. Since it was a zombie apocalypse and seeming the start of it when his father died, it could be that his father turned into a zombie and heo(teach) had to kill him, or his father was just going crazy and tried hurting/killing him so heo(teach) was forced to kill him.
