^ then the estimated sales this time are not correct Oo I saw sales around 28k... so I thought this single will do better... but I think the sales are still good
Not a dramatic difference, really, and it's still better than the first week sales of the previous two singles. Also, they had a few singles with Yuuka that didn't sell that well sandwiched between the ones that did, so I don't feel like Yuuka's presence was necessarily a factor.
