Kurenai
I've never liked Neji.
Of course, it's probably not fair for me to judge, since the first time I met him was the Chuunin Exam preliminary when he tried to kill one of my students, who also happened to be his cousin.
It made me wonder if he had a heart.
Apparently, he does, because apparently he now loves the same girl that almost died at his hand.
I'm more than a little skeptical. I don't like the sudden change of heart. All I know for sure is that I'm worried about Hinata, and that he is stronger than her. He could destroy her with no problem – and, if it came to it, I don't think he'd hesitate.
I'm trying to be supportive, because she seems happy, and he's taking care of her.
But if he ever lays a hand on her, other than to show her he cares for her, I'll kill him myself.
