From Kodansha:
All sugar, no spice, and everything nice. That's the impression the beautiful first-year high schooler and “heartthrob angel” class president Otogi Katsura gives to those around her. In reality, Otogi is brash, assertive, and has no problem calling out a jerk when she sees one. The complete opposite of her soft-spoken vice presidential counterpart, the equally beautiful and seemingly perfect Toki Ninomae. One day, when a group of boys try to hit on her at the train station, Otogi doesn't hold back and gives them a piece of her mind and to her surprise, Toki enjoys seeing this side of her. Not only that, it turns out the seemingly polite, put-together vice president has a hidden side of his own and Otogi now finds him more attractive than ever! Now “partners-in-crime,” Otogi and Toki agree to keep their hidden sides a secret from the rest of their classmates but could this shared, dark secret also bring them closer together.
