WHY DOES MANHUA PEOPLE DOESNT KNOW WHAT JELOUSY IS WTF

Lololol, we shan't question the logic of manhwa I was about to say he's never felt jealousy before but that's kind of impossible especially considering his background. But then again, he's also the guy who have a LOT of resentment towards the king. His resentment towards the king is the strongest feeling currently for him to even bother with other emotions... But that's also kind of unrealistic since no matter how strong one's resentment is, there should be other emotions in there somewhere ╮(￣▽￣)╭
