Let's be honest here, if Cain was there. Yahwi wouldn't have given Jooin a second look. He's basically of the "I don't want you but I don't want anyone else to have you." Mindset, Jooin's doormat tendencies are annoying; he put his foot down a few chapters ago and perceives Yahwi to have no feelings for him but yet is letting keep treating him like shit. Annoying, Cain may have come out of nowhere but at least he doesn't treat Jooin so rephensiblely.
