Second k-pop girlgroup to ever achieve this after Blackpink it looks like.
It's interesting what's happening with the sales of this album. Hanteo is far outpacing Circle now, although granted, the latter only accounts for the first couple days. That would mean it's for sure sold out in some regions and... Sure enough, it's sold out here in the UK, with retailers advertising more stock coming in throughout March (as late as 20th of March).
It looks like JYPE underestimated demand in a few markets or has otherwise run into problems with manufacturing/shipping. I'm hearing from a lot of people that their orders haven't even been shipped yet.
Either that, or they prioritised getting stock to the US as there seems to be plenty there, idk.
Whatever the case, the Circle number should grow continue to grow even into next month if this is true.
It's possible that my "30% decline from Ready to Be" prediction is wrong and the gap is going to be smaller. Either that or there's something wrong with Hanteo's count (it looks like Midsummer Nmixx's Dream also had higher numbers on Hanteo, but not only was Circle's initially smaller, it also got revised down, so something weird happened with the count).
