The same thing is happening to Itzy and Everglow

I liked most of both group's TT

Hmm, I think this might just be how perceptions change when a group becomes established. When a group debuts, no one has any expectations for them, so they're pleasantly surprised by anything they do. Random people in the general public want to check them out, talk about their visuals, etc. Unless they're a truly unusual group like BTS or Twice, the excitement naturally dies down a little as other groups debut and they're not so new and shiny anymore. That doesn't mean that they aren't slowly gaining fans or selling albums, it's just not a very interesting story for a group to basically be maintaining their popularity at the same level. People give more attention to rookie groups and songs that become huge mainstream hits, that's just how it is. Both the groups you mentioned are doing just fine, much better than most groups, they're lucky.

Edited to add: there's almost no way to have a comeback that doesn't disappoint someone, because everyone has different tastes. Some people will be mad that they switched to a new style they don't like as much, and others will be mad if they keep releasing similar sounding tracks. It's kind of a no win situation. If you're enjoying the music just tune the haters out.

Why make such clueless statements on a kpop forum where most people are slightly aware of sales and song performances

The La Di Da slander....

how is return of the girl selling?

They sold 50K in their last 2 albums.

I think people liked la di da a lot actually, but first and pirate were …. questionable. Personally I really liked mafia in the morning but was disappointed in icy and not shy.

OP is so clever to pit against each other two fandoms that have previously had no beef, and so many of you fell for it, hook, line and sinker, just to shit on a smaller group. Well done, OP.

So far, at ~28K. It's a similar overall trend so far, considering -77.82X-78.29 had sold only ~32K two months after its release. At this rate, Return of the Girl should at least match it.
