A/N: Once again, I bring you angst. I promise the free prompt will be fluff to make it up to you. *Evil grin*
Hands brush over glass. Words are whispered, then screamed, then sobbed, and then whispered again, hoarse, harsh, broken.
"You promised. You never broke a promise before, so why now?"
"You left me! How could you think that'd be helping?! How could you be so selfish?"
"Maybe you never cared at all."
"Please come back. I miss you so much…"
"… I… I love you… please come back…"
But then the words, along with everything else, stop. X's hand falls from the glass that will forever separate him from Zero, and he hangs his head as he leaves for the final time.
