he's a two-faced bitch. He ain't the real one and is dangerous.
We know real one is: kinda shy, clumsy, easy-going/not looking for conflict
so white jin is evil and he is scratched out from the list of potential true jin candidates.
ask-jin is probably orange or red jin (kind, caring, cautious ones = cinnamon rolls). Gut feeling says the orange one
purple jin has zero fucks to give.
as akuma-river analyzed (I love your comments but I can't leave a reply as an anon), any of the jins that gets an extra portion of hate/mindfuck from mr. rose is more likely to be the true one.

One more person I’m starting to dislike, is the one with the white hair I’m pretty sure he’s putting the nice face but he’s up to something bad.
I just don’t like his fake nice vibes.
