In Myowol-guk, a gathering place for rabbit spirit creatures known as 'myoin', the 101st prince named Nungso, who is a mix of human and rabbit blood and suffers from bullying, is given a task for his coming of age - to rescue the sacred and honorable 'Moon Rabbit' captured by evil humans and return him safely. Haru, a dalgona-colored brown rabbit imprisoned in an evil human's house, questions the description of being kidnapped and imprisoned as he was once a cherished pet. When Nungso meets the supposedly noble moon rabbit, he becomes fixated on the idea of creating a family with the young, white rabbit, and disregards Haru's claims of not being sacred or noble.
