I think ever since 3 nin she's been reluctant to work with the other girls. Except maybe Miki. I think maybe she feared she might get sucked into a group and lose her solo, much like what eventually happened to Miki. I notice her attitude towards the other seems a bit..formal...polite yet not overly friendly. This is a good point Mal, I wondered about this myself.
And Tette...you rock for those CMs!
That Pretz CM..lol! How is it Aya can be both so hot and goofy at the same time. I love her! Thanks for the up Masa.
