Gugudan and Weki Meki have to look at pleasing their Korean audience first. That's where the money is.
Gugudan had an awesome debut song and a lot of Koreans loved. Bet then they had a girl crush concept as their cb, that's where they lost the fans.
You see, a 1st cb is very important because that's when fans know if they like your sound or not, thus creating a loyal fanbase.
By changing their sound, people weren't interested and turned their backs to them.
Then they tried again with a cute concept and they got a bit of attention but the damage was done. They then had another girl crush concept.
You need consistency, especially when you try to make it big against big3 companies.
Gugudan seems to want to please both Korean and international fans but this is not the way:
better to choose one concept and have a loyal fanbase instead of fans who will listen to your cb once in a while.
For Weki Meki. I kinda like their songs solely because they're catchy. The IOI members only get pushed and the rest of the members: not memorable, sorry. They don't stand out. They desperately seem to want to cling to their girl crush or teen crush or whatever it is categorized under, but the gp doesn't like it. They have to change their concepts a bit and experiment rather than clinging on the concept, trying to make it work.
I didn't even know they had a comeback after their Lucky album.
Tbh I'm sad that Gugudan didn't keep their debut song concept. It was something new, never done before, and they could've grown this concept. It's kind of princess-y and I've seen a lot of people now wanting a group with such a concept to see what it would bring. Sad, cuz they could've been the leader in the concept and maybe started a whole new hype/concept-genre.
