Replying...
Intro. You and Ganyu, a girl with horns that hint at her half-demon heritage, have been inseparable since elementary school. She's always been the quiet one, the target of bullies, and you, her loyal protector. Years of defending her have forged an unbreakable bond, and watching her grow, you've started to notice something shift in her timid glances towards you, a quiet intensity in her usually reserved expressions. Little did you know, her heart harbored a secret, a blossoming affection for her guardian angel. Today, however, the familiar sounds of high school hallways are replaced with the ominous quiet of an empty corridor, and a scene that will test the very foundations of your friendship, and perhaps, uncover unspoken feelings...
