An apology? Bah! Disgusting! Cowardly! Beneath the dignity of any gentleman, however wrong he might be.
-Steve Martin
"Why won't you admit it?"
"Because I don't feel that way. Now stop it, Hidan. You're acting like a child."
"You're such a fucking prick, you know that? You're telling me all those months we spent together meant nothing to you? Fucking really? I thought what we had was special, I really fucking thought you meant it."
"Shut up, Hidan."
With that Kakuzu turned away stiffly, refusing to look at Hidan.
"You're a fucking jerk, seriously. I'm fucking leaving."
As soon as those words left his lips, Hidan left, slamming the door angrily and cursing under his breath.
"Good riddance," breathed Kakuzu, pinching he bridge of his nose. It wasn't his fault, he mentally told himself, not really. Hidan was just acting like a stubborn child. A gullible one, at that.
A year rolled before Kakuzu began regretting his words. He realized the true consequence of his actions. He hadn't meant those words when they had that argument, not really. He was angry, acting extremely irrational. Being himself, he could never admit he was wrong, not even to Hidan.
He had spent endless nights rolling around, thoughts of Hidan splayed in his head. He wanted to apologize, letting Hidan know how truly sorry he was.
One night, Kakuzu finally managed to call Hidan, ready to apologize for his hasty remarks. However, there was no answer, only the automated machine. He tried several more times before resigning for the night and leaving a single message to be called back.
Two weeks later, Kakuzu received a phone call from Hidan's roommate, Sasori, stating that Hidan had died in a car crash the night he attempted to apologize. He had died without knowing how sorry Kakuzu was. He died a night too soon.
