I'm not sure if the guy who was fighting with Taejoo was the neighbour, maybe it was that ugly guy who got his head smashed by Euihuyn.
In any case, the source of the neighbor's death was also a theory by a fan, so it is not certain yet
But I also feel like he's going to die in the end, and I also feel like this manhwa won't have a happy ending or a satisfying ending for us.
