it wasnt jealousy at all he sold his life and his clean hands to kill for a crazy zombii man who is scary and mental af only to get droped as if they are toys u can switch up. redhead got hurt sincce he harmed the teacher but he kinda lost like an eye and stuff abd its not gona stop there obviously he lost his mind since all his work is gone hes not in favor anymore. like a concubine wanting to live idk how to explain bether at the end u can call it stupid i just wanted to say psychological it makes total sence how ge reacted
Well it was mentioned that the hounds will get jealous at Teach if he went near Guwon.. they're all fighting for his attention after all, they all want to be favored by him, and yeah like a concubine fighting for the empress title. But it was still jealousy.. he even said "after everything i've done for him" he was gonna kill them both like a yandere typa shit because he couldn't win Guwon's affection and he's been humiliated by getting punished by Guwon multiple times.. he didn't just do it for survival. He'll die either qay if he successfully kills Teach. None of the hounds are normal.. only the civilians are.

That red head was a waste dude, why'd he have to be so dumb. He was hot too, dawg gotta ruin it with a walnut brain.
