English
We’re playing a vivid symphony: a Rainbow Symphony

The reason scars don’t heal when you try to forget,
Is because trying to forget makes you remember them.
I go around, and around, and around, and around in circles.
But I think it’s time to stop spacing in front of a clock that’s already stopped.

The more powerfully I feel that I want to be with you forever,
The more I lose the ability to stay in one place.
I’m the rain, you’re the sun, so let’s join hands;
We’re right here together!
We’re playing a vivid symphony: a Rainbow Symphony;
I’ve stumbled upon sounds I wasn’t able to produce alone!
Crying, laughing, with a do-re-mi-fa-sol;

symphony of resounding emotion.
