It looks like she's kissing herself. I don't know. My first thoughts were that Avex is trying to stir up controversy to boost sales ya know? Sorta like they're making a provocative cover to sell more. I don't know.
But I'm sure there is some hidden meaning behind the cover. Maybe Ayu will say something about it.....

By the way, didn't Namie Amuro have a PV where she "kissed" herself? lol
