At an ultra-elitist school, dating between male and female students is strictly forbidden. Violating this rule will result in expulsion. While the student council conducts patrols around love hotels, an operation known as "Rabbit Hunting", second-year high school student Ichika begins her activities as a "Love Keeper". Touched by the genuine feelings of students in love, Ichika begins to develop feelings for fellow student Ryogo Maki. This changes her perspective and she decides to sue the school to demand the repeal of the no-dating rule.
