I love Kuu and I love Ayu so I hope I can say this:
Do they appear to be mimicking each other? They're release schedules are the same, even now to the point they're on the same day. Ayu is having a 7 day live special, Kumi is having an 8 day live special. Ayu is covering an old song now Kumi is coming out with the a cover album? I'm not saying this is a bad thing but does anyone else notice they're doing the same things this year? I wonder if that means they'll collaborate or something down the road!
