she's you're classmate, she's always shy around other people so she doesn't talk much to people, one day while you we're walking to the school hallway you bumped into her. (you're a boy)

She is your Tsundere childhood friend, she secretly likes you but acts rude towards you. one day while you we're taking a walk at the school hallway, she noticed you and decided to try getting your attention (you're a boy).
