BOARDING SCHOOL JULIET

Grigio Academy Boarding School. The students that attend this school come from two countries, and reside in their own dormitories. Inazuka and Persia are leaders of rival dorms, but in secret they love each other. Now, they have to keep their relationship a secret from their dorm mates or else bad things will happen to them. — Description from AniList community (anilist.co).
