Kuu I can see, but Ai?
And ayu won't get "bumped off the throne" anytime soon
If noone has noticed, Jpop Queens don't fall off the throne, they step down willingly. Look at Namie, she went on a hiatus voluntarily to pursue marriage, that's how ayu got her big break. Had Namie not stepped down, ayu won't have had that shot at Queen. I bet the same thing will happen again. So no chance, Kuu and Ai, you gotta wait it out
