The title is Metamorphosis. Living in a world through glass that has lost its color, I look at the outside world from inside a chrysalis in a cul-de-sac where time has stopped. It spends its time dreaming of the day when it will metamorphose from a chrysalis and become a butterfly. That's what this song is about. I've always been a shy person with a communicable disease, but I've finally lost my mentality. I am a complete indoor person who hates the outdoors, so I am in a situation where being cut off from the outside world is not really a problem. The world inside the chrysalis is like spending a winter night in the snow, full of silence. The day will come when winter is over and the chrysalis will metamorphose into a butterfly. I hope that day will come, filled with hope like a rainbow in the sky after the rain.
