Kakashi knew that he had found his soul mate in Sakura. It had taken about a year and a half to convince her of the same thing. If anything she was more stubborn than he was.
There were other things that they had in common. They both felt the need to keep their apartments immaculate. Kakashi wasn't surprised to sneak through her window to find her scrubbing her floors at seven o'clock on a Saturday night.
Both of them didn't like staying in hospitals. Kakashi felt fine about visiting someone, but as soon as he was admitted he was making plans to check himself out. Sakura couldn't stand being in the same building as injured people without helping them. It was a common sight to see her down in the emergency room in her hospital gown after recovering from a serious mission.
There was one thing though, that Kakashi had taught Sakura to like. In the months that they became involved with each other, they spent quite a large amount of time in the bedroom going through Kakashi's Icha Icha books. Sakura said that he had corrupted her into a pervert, but he shrugged.
"We may be perverts Sakura, but at least we're perverts with substance"
