Another similarity? Well, they had both trained under a legendary sannin! Sure, the one he had trained under had tried to destroy the whole village at one point and the one she had trained under was now the leader of said village, but so what?
Of course, they had their differences. No one can be the exact same. It would ruin their personality and attitude. Of course, he had more of the latter and almost none of the former, she could deal with that. Heck, she had drooled over it along with half the female population when she had been young and naive. To tell the truth, she still did that now...only rarely though. What can you say, old habits die hard.
They had also been on the same team. With the ever-punctual copy nin and 'future Hokage' as the other likes to proclaim. There was another similarity! Another point for the two and and a big goose egg for...'them'. Them being all those nosy people who had too much time on their hands. Heck they were even starting to compare the two of them to things!
They compared her to the colour white and him to the colour black.
They were wrong about that too. She definitely wasn't 'white'. White was pure. White was...white. She was not white. One can not be pure when they live their life as a ninja. Her 'white' hands had been stained red by blood. She was more of a pink, maybe. Like her hair. Maybe not.
He wasn't 'black' either. No one is ever purely 'black', except maybe that snake that had once been his sensei. If any colour would pop into your head when you said his name, it was red. Like his eyes when he's serious. Those eyes that haunted her at night when he was away. Maybe he was red. Maybe not.
Point being, she was definitely not white and he was definitely not black. They were more like grey, actually. Nevermind the red and the pink. Another similarity! In your faces, all you who oppose! Yes, they were definitely a grey.
Even if their shades differed.
