It's most likely Tehir. Tehir has been obsessed with Jin for a long time and Kimoto wants to get over his crush on Tehir because Tehir has changed/is an asshole. But it's hard to say because as of right now, They haven't spent any time together.
Charin is dead, and we have no idea if it's actually possible to bring him back as himself. But, if he DID then I think Jin would choose him every time.
That evil green dude is trying to kill Tehir to bring Charin back to life so, I don't know anymore.
Idk I feel like it’s impossible to know bc we as readers are missing information. Jin’s past sill remains a mystery to us. And who Jin really is …ig. I feel like we’ve only seen surface level and bits/pieces. Feels like we’re all just waiting for that moment when everything clicks into place...like who even knows if there is an endgame
I wonder who Jin is going to end up with??
After reading the recent raws, it seems like other guys are paired up already
