I still think they used old pictures for the album, since in those pics she has exactly the same hairstyle as in 2004 x___x If she cut her hair short, at least she'd have a different kind of cut, right?? Her hairstyle has varied so much, it would be weird if she went back to the exact same style she had before
Haha

, exactly what I have thought since I saw the album cover. Those pics must be from 2004 (maybe it's a pic from the album that was supposed to be released in early spring 2005).
About the single cover, she looks just LOVELY!!!!!
And about the "long hair, short hair" thing, Nacchi is cute no matter what she has, but if I would choose between long hair, short hair, I would say long hair....

But to be honest it's not that important. Go Nacchi!!!!!!!!!!!!
