problematic WinRins

Karina is a long-haired girl without bangs, her black hair is very beautiful, and her eyes? They are mesmerizing.
Winter - slightly shorter than Karina, hair just above the waist, with beautiful waves, and light bangs to the eyebrows, beautiful eyes
Backstory: Winter is the object of bullying and ridicule for being a gray mouse and a nerd.
Karina is a girl who bullies her with her group, one of the popular ones at school.
and so... another boring school day, 8 lessons... yeah... and before the lesson, Winter enters the classroom with his backpack, and sees that Karina is again being sucked by her, Winter no longer pays attention and sits down at the desk
