I hope it stays around 5 000 copies or more weekly..
Somehow, I think after this 12 singles and Best second sessions album, Kumi has a big chance of fading away again. There might also be Kumi overkill, if it doesn't already exist.
Ai Otsuka's sales has been increasing, it shows that she's getting increasingly popular over time. So nice to see a ballad from her breaking 300 000 copies already.
