JM being with an American doesn't even surprise me. I don't know if they are still there, but a fun piece of verified info is that BigSh!t used to have photos of JM and Shannon Williams together all over the company in the non-public areas of the building. Their relationship was like the golden relationship, lol. Granted, Shannon is British/Korean but basically she's a foreigner and therefore him being with another foreigner is plausible.
I don't think JM is bi either. I think he's gay. Yes, he has been with women, but a lot of people who are gay/lesbian will date the opposite sex due to being in denial.
Tae is fake and I wish more people could see this. Like, his behavior isn't Tae being a "precious bean", it's total BS. YG even said that when he first met him he thought there was no way he was real. Tae also has conversations with himself, not a "hearing voices" sort of talking to himself, like childishly playing pretend by himself, usually while he does chores. It is super weird and for some reason the other members and his fans condone this.
