The sky we saw that day, the crimson sky; do you remember?
We made a promise, wrapped in the early summer breeze; the two of us huddled close
Stretching shadows hide behind that excessive smile
So I choose to replay that imperceptible pretense
I keep waiting for the unshakeable notice on the table
The empty night, the morning that won't come; it all became clear
The sky we saw that day, the crimson sky; will you remember someday?
Embracing a promise that could not be fulfilled, the two of us set out
