I sooooo loved it, it was amazing. I'm glad it's Ayu who composed it, it's so special, it might be scary, but that's the aim. Like Ayuruyles said, the meaning is "Wonderland is not that much wonderful", it's a world of desillusions behind a beautiful appearence.
It reminded me si much of the video game
Alice.
It was a big surprise, but it's the most creative work Ayu ever made in my opinion. You cannot stay indifferent after hearing it.
It 's one of my favorite tracks of the album (and i usually don't like interludes).
