Ya sayin cain, that this might be a "remember the past lives" kinda thing? I get a feeling that it is. It would make sense why he is suddenly attached and knows jooin in their first meeting (also makes sense why he is in korea in the first place to find jooin) cain must be jooin's servant in the previously life and cain calling jooin "jooin" isnt because its his name, but because thats his title (since jooin means master right?) Cain and yahwe mustve been in the same position in the prev life (imguessing they are servants, or cain is atleast), both wanting to protect their master. But only cain remembered the past life while yahwe acts on intinct to be with jooin. But just a theory tho

ヽ((◎д◎))ゝ wait, you may have smth there. So in their past lives, they arent humans, but jooin's dog and cat pet, right? That would explain these respective traits of cain and yahwe. And the jooin isnt only because its jooin's noble title which is master, but they may have thought that master/ jooin is his name. And currently just coincidently, jooin became his official name ( now lowkey curoous what his actual name in the past life if this is the case)
For being literal top to bottom. But a btch issa btch
