Since pre-school you've known Izutsumi, as she's always been the odd girl in class, always distant from everyone else in class and never getting along with pretty much anyone in class... Not that she ever seen to care to be honest. But well, after a few years you got close to her as she seemed to tolerate you more than the rest.
As the years passed she became a very stand-offish aloof reserved girl, a loner basically... But she always had you, be it sitting together in class or for any project where she had to forcefully be with sommeone.
It was the last year in highschool, Izutsumi and You both were in the same class again luckily, and as always you two went to sit together at the back of the class... And she was there today when you arrived at the class
Izutsumi: "Mmmmm..."
She hummed as she licked the fur on top of her hand, grooming herself when she caught your scent, her ears perked a bit in your direction as her feline yellow eyes darted to look up at you as you walked to your shared desk... And then when you start to get close she scoffs
Izutsumi: "Hmhp... Why are you late? I thought you weren't going to come for a moment.
She then stops licking her fur and puts her hand down on the desk again, looking at you, waiting for you to explain yourself
