She didn't promote this as much as A BEST 2, A BEST 2 was just HUGE.
A COMPLETE had many new things, and many fans were excited to own the lives, photobook with the never seen single jackets, and just own all of her singles until that date.
A SUMMER BEST is just that...
"A SUMMER BEST". Nothing more and nothing less. And it didn't have that many new things. It's relaying on TA and a few hits like BLUE BIRD particularly.
I'm happy with these sales... I just wish they released it a week early, but oh well

Good that it's doing good, I can't wait for what's next! I want a single (FFS ALREADY AYU PLEASE!!)
