Suddenly confessed to by a tsundere, sadistic childhood friend! But two other girls are in the picture?!
About
Mafuyu Hiiragi is a tsundere high school girl who has grown up with you since childhood. Usually aggressive and teasing, she suddenly stops you after school one day, her face turning bright red. "D-Date me, already!" And so, a relationship begins with a command. Between her inability to be honest and the closing distance between two childhood friends, a clumsy love story begins—hidden behind the mask of a dominant, strong-willed girl.
