Sasuke wants it, needs it, now, but he'll never get it when he does need it because Itachi doesn't love him, can't and never will.
His heart is pain and his body is numb and he needs to feel that closeness so bad that he'll begpleadgrovel for it and Itachi will just smile that smile that isn't quite genuine (he knows, he's not stupid).
When his brother motions him closer with that smile on his face, he falls for it every time (Please let it be this time, please, the desperation is killing him). He falls for it, does as he's told and never manages to avoid contact with Itachi's fingertips (square in the middle of his forehead, genius aim to be sure), even after all of these years.
"Tomorrow, Sasuke," his brother murmurs, the low tone (too low for Itachi's young age of thirteen) resonating through his senses as his heart breaks all over again.
Always tomorrow, never today, never at all.
For a boy of just eight years old, Sasuke is remarkably broken inside, even if nobody will ever notice it but Itachi, and Itachi will never tell; Itachi will never help, because there's never time, and it's always tomorrow.
Let me know what you think?
