Boarding School Juliet takes place at Dahlia Academy Boarding School, where students come from two fictional countries known as the "Nation of Tōwa" and "Principality of West". This academy segregates its student body into two dormitories, which reflect their nationality: the "Black Dogs" housing those from Touwa, and the "White Cats" housing those from the West. The story follows Romeo Inuzuka, the first-year leader of the "Black Dog Dormitory". Romeo has had an unrequited love for Juliet Persia, the first-year leader of the "White Cat Dormitory", since childhood. Initially hesitant, Romeo decides to confess his love and resolves to change the world if it means staying by Juliet's side. Juliet, impressed by Romeo's determination, accepts his love. However, now both Romeo and Juliet must work hard to keep their relationship a secret from other dorm mates while trying to avoid trouble.
