NJ is mean, plain and simple. I feel bad for her too. You get to do that thing with an idol you like and it turns out to be really awful. Granted, any time we choose to have sex with someone there's a chance it won't be good, especially a ONS, but we don't deserve to have an abusive experience.
HS not being "happy" didn't really shock me, necessarily, but it wasn't what I expected. And that's good, really good. It does show what he's keeping inside and if anything, letting it out was healthy for him. Aside from maybe NJ, I don't think the other members wanted what they got with joining BH. They're often careful about what they say or allude to, because they've been coached to be careful, or worse warned and punished for saying the wrong things. Despite that, Jin pretty much says whatever he wants, he even called out his own bandmates in an interview about the BE album because all his input for the album was rejected. He didn't specifically identify which band member it was, but I think we all know who it was.
YG has a also been super vocal over the years and hinted at a lot of internal problems. In general he's verbally unhinged. He's diplomatic in public most of the time, and wise, but this is the same guy who bitched at an American interviewer in Korean over a dating question (which NJ translated as "He says he's single", lol). He's also been open about their almost disbandment in 2015, and has even called out @rmy for their nonsense belief that BT5 were barely having any success and didn't get many opportunities early on. YG was like, "We were doing well but we weren't seeing the success we had hoped for". He is also the only member who's been open about his sexuality, and I seriously think the label told him to say that it was a mistranslation just to make discussions about it fizzle out. I get it, SK is stupid about homosexuality and coming out is dangerous but it sucks to be in a position where you are forced to lie about who you are, especially after being so honest. It makes him look bad without it being his fault.
Speaking of coming out, what are your thoughts on the bi colors during HS's performance of Equal Sign? I was surprised but also really happy to see it. I had always thought he was gay instead of bi. I've never gotten vibes from him that he's attracted to women, but during that performance he was definitely flirting with the female dancers.
