This is Hybe's biggest problem: they don't know how to sustain the hype around their groups in the long term and expand it further. Their groups start off strong but then suddenly decline. Enhypen has the potential to become the biggest 4th generation bg; their sales trajectory is better than anyone else's.
Then we have Txt, the direct junior group of Bts. Their debut hype was one of the biggest in Kpop. Their sales were much bigger than Stray Kids' when they just debuted. Now, the gap between both groups' popularity is huge, and the difference in their sales for their latest album is almost 2 million.
This almost happened with Bts, but Armys are just that dedicated of a fandom, doing almost all the work for BigHit, from promoting to even translating new materials to attract new fans.
Where has the hype for Tws gone when their debut song did so well? Riize is frequently on the front page of hot topics. As for Bnd, they're taking the slow but steady route, but the group itself hasn't made much noise.
So, I wonder how it will go for their girl groups. Will it change?
