Well, I think it's bc of his loss of memory and confusion at the time + Charin is different from Tehir in a way.
Tehir acted nice to everyone while feeling superior and casually dismissing everyone's feelings, but with Jin — who he viewed stronger than himself — Tehir was always trying to get in his good side as if Jin was equal with him, and THAT pissed Jin off, especially because the later, apparently, appreciated Kimoto, but Tehir didn't and even would use Kimoto's good will (childhood bed scene) so Jin, obviously, wouldn't view the asshole in a good light.
While Charin genuinely liked his family made up of street orphans.
wow this is top tier world building i love the author!!! i guess we're getting stories for all of them. i didn't expect this route for tethir tho. i miss charin but i doubt jin x charin v.2 will happen. i still think jin still has his original personality but since he's smart i don't think he inherently is a monster.. maybe more neutral? i skimmed the raws a bit and it seems like tethir was doomed anyway? idk
also why doesn't charin have a halo? and why did jin like charin but not tehir lol he's literally like another variant of him who's more humanized. both with inflated egos/superiority complex.
