At this part it's just like  the "lily if the valley" jooin is just too dumb to understand that yahwi didn't just wanted him for s**, yahwi do actually cared for him. All those gifts and treats just for him to choose a random like Cain literally stepped in jooin's life like bro? Just bc of a reincarnation doesn't mean he has to do everything again and again Cain didn't have to be a fuc**** puppy that'll always follow jooin and stepping onto yahwi and jooin's relationship. Honestly, Cain just made everything worse, if he hadn't been a bi*** then yahwi and jooin's relationship would be fine.
