I've always thought bg's goofy personality was just a mask. If you watch him in their talk x today episode before they debuted he was so quiet. Almost a completely different person to what he is now.
When I used to be a fan of them I remembered when I first discovered them and I saw that bighit tried to mold bt.s's members personalities to them. For example
yeonjun is like v- cocky personality, modelesque
beomgyu is like jhope and jin- sunshine/ energizer of the group, doesn't really get alot of lines like jin or opportunities but both spend alot of time with bang pd (which i find sus)
huening kai is like jk- cute maknae role, looks up to hyungs
taehyun is like suga-serious, both don't really like doing fanservice
soobin is like rm- leader, clumsy, a bit shy
Sometimes I wonder how things would change if fans got to see who they really were and what their real thoughts were. It must be tired for beomgyu to act like the mood-maker 24/7. Like I said him now vs that person in the video I posted are two completely different people. I don't know if beomgyu has gotten over his depression but he seems to be masking it pretty well lately. It was pretty evident before that he was going through something while the members tried to cheer him up.
