I saw that sheet and thought this might be a release for the first half of the year. I can see two different releases, like A BEST 2, but tbh I don't know how I'd divide them cause the happy/sad songs rate for Kuu isn't as balanced as ayu's lol Maybe something à lá W FACE with a bold/upbeat edition and another one with the balads and cute/happy songs. It could be too similar but maybe she wants that.
It could even be paired with the reLIVE DVD, one edition has the Black Cherriy concert and the other having the JAPONESQUE one.
But who knows

Maybe she's done with the paired releases, since reCORD already broke that pattern.
