^I don't wanna know what she came up with.
I wouldn't be surprised if lots of artists owned at least some of their works...kinda like actors owning their own movies and authors owning their own novels. Of course, some don't because they find it weird or embarrassing, but heck I would own all my own stuff. I'd be too proud otherwise. XD
But no, I haven't heard or read anywhere that Ayu does...
