Real talk, all honesty: Sometimes army. Sometimes not. It's kind of complicated. I'm not sure I'd call it regret because I'm happy with being one but maybe just feeling embarrassed a lot.
Like... there's a lot of army that are a bit too dramatic about things and that kind of conflicts with my 'chill and go with the flow' attitude a lot. Maybe it's because I'm older, maybe not, but I always feel awkward when people start getting a little too needlessly aggressive? However, as having been an army since 2015: I do know that people have hardly ever been nice to the fandom or the group. Other fandoms had always loved to stomp all over bts/army like their own personal punching bags. It's all the rage. So, I mean, what do people expect? You keep poking the bear and it's going to keep being defensive.
That being said. I have met so many amazing fellow army, funny army, those with huge hearts and good heads on their shoulders. These are people I have always loved the company of and I'll never regret supporting BTS. They have helped distract me through hard times and have given me much laughter when I've needed it most. I'll never regret that.
