I actually think that Ayu showing people more of her thoughts and behind the scenes of her career is just what she needs.
For a while I felt like it was hard to get to know her outside of her music and tv appearances. But now that she has things like instagram, I feel that I am closer to her and get a small window into her mind and day to day life.
But I don't think her posts are meant to be taken so seriously and over analyzed. It's not worth getting upset over.
