I don't know. I did see an article about it and kept it in mind. First week Circle chart is not much higher than Hanteo (although the tracking period is different - only three days on Circle). Usually there'd be a huge gap between the two for Twice.
If the gap was going to be the same, Twice would easily break 2m this comeback, but that's unlikely because usually JYPE announce record breaking preorders, and they didn't announce anything this time.
For what it's worth, sales are down for everyone... Except G Idle for some reason. I think the Covid boom might be wearing off, especially as economies are tipping into recession in some places.
