Did OMG success pave a way to cute/bubbly concept to be popular again in kpop?

I don't think so. Which rookie groups are you refering to?

I don't think it's because of OMG but rather there's a hole in the market now that's Izone's gone...

remember they're last few albums sold what 300K+ so there's a huge market there...

It's because of the market void

Did you miss all the hate TWICE gets for doing exactly that :P

I don't consider Omg songs as cute, their style is more of a fair taille, fantastic, super natural type of concept so i don't think it's fair to put them in that category.

Side note: Lightsum debut reminds more of Rocket punsh debut than anything else, it's like a mixe between a Itzy concept and Red Velvet concept

Same. It's more an innocent concept rather than cute.

They were always popular in SK, Twice were just so successful through constant with it that they overshadowed most of the others. As soon as they stopped a gap was left.
