Buy the manga and die of cuteness overload.
At our high school, Haimiya-senpai is famous for being terrifying. It seems to be because of her intense look and her blunt way of speaking... Flashy piercings everywhere! Long grey wolf cut hair!! And an intimidating regional drawl!!! But for some reason, this scary upperclassman is only kind to me──────!? I wonder why... when I'm with you, my grey days start to fill with color... That's how it feels.
