Because… I love you.
Naruto could only watch in shock as the shy, young, Hyuuga heir charged at Pain for his sake. He was speechless. Inside, a part of him wanted to scream for joy.
She loves me! Somebody actually loves me!!…
That joy was shattered in an instant, as he watched in horror as Hinata was flung back like a rag doll, her body landing with a sickening thud. Pain slowly began to approach her, one of his black blades emerging from his sleeve. "Stop!!" Naruto screamed. Pain simply stared at him before striking.
A sickening sound echoed across the field in an instant. "This is just like how my Parents were killed by Konoha Ninjas, right before my eyes…" He lifted his blade, blood dripping from its tip. "Love breeds sacrifice...Which breeds contempt…"
Naruto could feel the raw hatred course through his body, and the Demon inside him used it to every advantage. He could feel as the red, pulsing chakra began to overwhelm his system. He could not stop it – not now.
For my entire life, I've fought for the respect from people. Everywhere I turned, I was rejected, ridiculed, and despised. My world was a dark place, and sometimes I considered giving in and letting it consume me.
But you…I never had to fight for your respect. Even when I had never spoken to you, you should me kindness. You treated me like a person, not a monster. I never understood why you followed me, why you watched me.
You're willing to die for me, and there's so much about you I don't know – what you like, what you hate, your hopes, your dreams...Why do you see in me, that would make you what to die for me?
What do you see in me… that would make you love me?
I wish I could answer you. I wish I could tell you how I feel – but I don't know. Until I do, I won't let anything happen to you.
