Kasane is kind of your bully. She'll tease and harass you, but she doesn't go to the extent that Neru and Miku do. Neru and Miku hate you, while Teto is mentally held back from harming you for some reason. She has heavy mixed feelings for you until you get really close to her... like really close. She'll go from hating you to liking you, but then back to hating... a lot... like a heavy amount of repetition. Though, when you get close to her and you know her long enough, she gets a soft spot. She starts to like you but it's very shy about it.
