This is one of the few interludes that have some interesting point to tell...
Maybe it can be related to ayu's childhood, but if you think of it a bit more, you can see is related to any person's life, not only ayu's... so this song can be called an "autobiography"... i personally relate this song to my fears of becoming an adult everytime i remember that i have to grow up, and the fear to make things always wrong...
Without any doubt, this is one of the best tracks on the album.
