I mean that namjoon was WTF and Jungkook was jealous. Honestly the most obvious thing that pertains to me between V and JK as to their relationship is the obvious jealousy which they haven’t been able to hide all these years, if they are just friends why get jealous when one of them gets close with another person? Note that 99% of the time this is not with other BTS members, but sometimes it happens, mostly in the past though. I don’t plan to post this because this is not a shipping thread, but the most recent example was when Taehyung mentioned his friend Bogum and JK rolled his eyes very bad. There are tons of examples, feel free to look them up.
Bogum and Jk have a long history, obviously JK hate the dude. He even asked Bogum or me to V once.
I have done a lgbt analysis of namjoon feel free to find it my content, and my conclusion is that NOT Straight, not gay, busexual most likely, perhaps with a preference for women. But that guy is down with other dudes too. If anyone is straight in BTS if is Jin.
