Also if you want to get to know more about their personalities i recommend watching fan made compilations, BbyYeonbin is a good youtube channel to start with. If you want to get into txts content specifcally though, i recommend their variety show "TO DO" its probably my favorite content to watch from them other than their music! ❤
kpop is interesting because when I first got into kpop I was a younger stan of BTS and all of the 3rd generation kop groups mostly age wise but now with 4th and 5th generation kpop groups I'm a few years to multiple years older than the members depending on years... again it 's a strange concept...
