One day, the rulers of the Demon Realm, Angel Realm, and Human Realm meet up and discuss and discuss an exchange program. This program would have four members of each realm go over to the other two realms for four years. Uratanuki soon gets a letter about being selected for the exchange program. Having no choice but to except, he finds himself in the Demon Realm. He meets the demon king and his seven sons. He, his new human friend Amatsuki, and two angels; Sou and Eve find themselves living in the Demon King's castle. Little did Urata know that the seven sons would all be fighting for his heart. And maybe it's not limited to those seven only. This is will be a heavily romantic story. And it will also be interactive based so you get to make choices! Your choices will be what changes the story! I may make multiple stories or chapters for the different routes. Anyways, hope you enjoy~! Collab with @mysteryjessica
