It was raining, when you died. You promised me that you will never leave me, and yet you did. I have brought Sasuke back with me, and now we all are standing here, crying. Sakura just stood there, not looking at anyone else apart from the flower she laid on your grave. She gave me a letter from you at the end of your funeral, I guess I should read it now.
Dear Naruto,
I wish I could stay with you longer, but I guess this is it for me. Take care of everyone, even Sasuke (if you ever find him). I know I broke my promise to you, but I'll sure make it up to you soon. Ahaha... I feel stupid. Writing all of this in a letter, I don't think you'll ever forgive me. Naruto, please don't grieve for too long, it'll just make you feel a lot worse. Just to let you know, I'm living my last minutes in the hospital alongside Obito. He's dying too, you see. At least I'm not alone right?
I know in this letter I'm saying such stupid stuff, but I think you'll understand what I'm saying. If you don't (cause you're stupid), I'm basically saying I love you, with all my heart, and never, ever forget that. I'll always be with you. Until the very end.
From: Hatake Kakashi, your beloved Sensei.
