It's not just that, lol. I've seen the Suga thing around a couple places online (one particular batch from December also mentions the Mina/BamBam thing and Hwayoung actually being a snake so they're at least vaguely reliable) and a lot of Suga stans are pretty confident about it. The smiling thing I mentioned was a personal thing. It's hard to explain but when people are dating they act much happier and they get this kind of... glow? I dunno. It's sort of intuition. I've seen it happen in real life, and other people felt the same about Kai and he ended up dating Krystal. Also he and Jin are the only ones who could probably maintain a relationship, haha.

I understand if you're a long time fan it's natural to be protective of them, but being protective doesn't include dragging other groups. EXO may not be as involved in their music as BTS are but they're incredible performers with some insane vocalists. BTS's weakest area is their vocals. That's not to say that they're bad vocally, but they need to be more realistic about their limits. Jimin is often out of breath live and V can't hit half the notes he's asked to purely because they're out of his range. As a fan I hope they improve vocally.
