I feel it at my fingertips. But this warmth will fade fast and far away, and I'm screaming. Don't erase these thoughts left for scrap.
I can find our olden days again. But the way they were is blurred beyond all hope, and this solemn wish we swore that we'd never let go falls apart at the seams.
Even pain is lost on my body now. Here in the dark, one wanders alone, "There's no coming back," so they say, and so they keep denying in a cold, frozen, passing plea.
Someday all, and the anger, will disappear. We'll separate, and the ice will melt. "Once more," for here, we can still smile together. This is what I've left to you in my final words.
