Kishuku Gakkou no Juliet

Dahlia Academy brings together students from two rival nations, separating them into dormitories that treat each other as sworn enemies. Romio Inuzuka leads the Black Dogs, while Juliet Persia leads the White Cats, so everyone expects their encounters to end in conflict. In truth, Romio has loved Juliet for years. When he finally confesses and promises to change the world if that is what it takes for them to be together, Juliet accepts his feelings. Their real struggle begins after that: building a relationship in secret while surrounded by classmates who would consider affection for the opposing dorm a betrayal.
