exactly Moocow! On the both side the prospective it's a toxic relationship. I really don't understand people who prefer Cain just because "he's a little bit better than Yahwi", we're all reading the same manwha or what?
Every chapters where Cain appears he manipulate Jooin like "oh my gawd you're hurt? i'm here for you but at the same time i confess my feelings to you so you can feel like sh** not to reciprocate it, repeatedly. Oh and i'm taking advantage on you but hey, i'm better than Yahwi because i'm an angel during s**". C'MON
Spoiler!
i don't know how many bl i've read
