It's herself
she's just herself. People say that they are always just themselves but...I don't think it's as easy as it seems.
Ayu's always honest and true to herself, even as far as to call herself selfish. She knows, and I think understands the repercussions of that, but she still can't be anyone but her. I think it's interesting that Ayu has grown as she has, and I think she has a lot to thank from her career for that. I think that if she had ended up as an actress or model, she might not have the same outlooks on things as she does now.
She also has a wonderful sense of humor...You'd be amazed at how much that changes things lol
