(+ NewJeans)
This really puts on perspective how extraordinary this year has been when it comes to girlgroups debuting.
It could be argued that the only relevant group debuted last year for the current K-Pop's landscape was IVE (and they debuted pretty late, on December). We can also see 2 boygroups with decent physicals on the top 3 that seem to barely have a name outside their fandom and 2 girlgroups (Purple Kiss and Billlie) you may have heard of, but are not mid-tier yet on the big girlgroup sphere.
On the other side, we have seen this year already the debut of Kep1er (from Mnet show), NMiXX (JYP), LE SSERAFIM and NewJeans (HYBE). All of them groups with a very solid fandom since the start, and the ones from Hybe with also great performance on korean charts.
To put this on perspective, everyone's talking about who'll get the rookie awards this year because of these debuts + IVE is also on the talk because they debuted late 2021. Aespa debuted on late 2020 and they got them on 2021. Do you guys know what girlgroup would have got them last year if Aespa didn't exist? StayC. And what girlgroup got it on MAMA on 2020? Weeekly. This shows how important timing is and how it can affect the way a group is looked at success-wise.
