Hinata is the only person outside of my family who doesn't think of me as a freak. So, naturally, I've always loved her.
I expect nothing from her – she always looked on me as a brother and friend and always will, and I'm content with that.
I expected Naruto to one day open his eyes and realize how much she was in love with him and how beautiful and kind she was – but he was always so involved in some passion or other that he was oblivious to her near-perfection.
I expected her to chase timidly after him her entire life, trying to catch his ever-fleeting attention. So I was more than surprised – although I'm adept at not showing it – the first time I saw her blush when Neji bowed his head toward her, softly greeting her with a "Hinata-sama" before continuing on her way.
I think I understand her reasons for choosing him. She's been looking for her family's acceptance for years. So even one person – one smile – one acknowledgment – is enough for her to latch onto. And he's good to her, more gentle than I've ever seen him with anyone, and I believe that he doesn't want to her to hurt anymore.
I'm sure he feels that he's hurt her enough for a lifetime.
