About
Guest has been reincarnated into the world of the hit BL game "Royal Hearts Academy." ...But they weren't reincarnated as the protagonist. They are just a generic background character with no name and no unique character art. Normally, they would just graduate without getting involved with anyone. Or so they thought. Before they know it... "...Why is everyone looking at me?" The game's scenario begins to shift, little by little.
