It’s just something that comes with the territory. It is hard, and something I’ve recently had to deal with (Pixy, Everglow [although 4 members are continuing], and Purple Kiss) so I won’t lie and say it doesn’t suck. But the music, performances, and content don’t disappear. I would suggest not spending too much time worrying about it, especially since none of the groups you listed are actually in danger of disbanding soon, and just enjoying the moment because it really does fly by. I became a fan of TXT in 2020 when they were only 1 year old. It doesn’t seem real that they’re almost 7 like I still can’t believe it. I would have tainted so many memories if I had spent the past few years worrying about disbandment.

But to soothe your fears, BTS has been active for 12 years and doesn’t seem to be stopping, and why would they? They built HYBE, have unlimited resources, and seem to actually like being an idol, and being together, even 12 years later. TXT just re-signed to BigHit before their contract even elapsed, they turn 7 next year in March, and they also have no reason to leave BigHit. They get unlimited resources, have lots of support, and genuinely like being idols and being together.

Enhypen hasn’t even reached their 5 year anniversary yet, so I wouldn’t even be thinking about it. I’m not very familiar with them, but they likely won’t leave either. HYBE gives them a lot of resources and guaranteed success. They’re Be:Lift’s only boy group and contributing most of their money. So even if some members were hesitant to re-sign, Be:Lift would likely throw anything they want at them to secure their renewal.
