Absolutely shit writing in my opinion. The smart thing to do is to verify yourself on how they're doing and seeing how they're like for yourself. Just taking everything at face value without making sure you verify everything, especially for kids who were supposedly the apocalyptic boss monsters that he wanted to prevent so much, he sure as fuck is flippant with how he's dealing with it. There's a huge disconnect with what he says he wants, and how he's actually acting it out. I dunno why there were people saying this manhwa was decent, it seems low quality writing honestly
