Lyrics:

It's a blue world without you
It's a through world alone
My days and nights that once were filled with heaven
With you away, how empty they have grown
It's a blue world from now on
It's a through world for me
The sea, the sky, my heart and i
We're all an indigo hue without you
It's a blue, blue world
It's a blue world from now on
It's a through world for me
The sea, the sky, my heart and i
We're all an indigo hue without you
It's a blue, blue world
