When Nora arrives at the ancient Harcourt Manor to apply for a nanny position, she is greeted by three mixed‑blood children with extraordinary abilities: Theo, who possesses short black wings, Iris, who can manipulate silver threads, and Milo, who has a long tail. The three children form an alliance, vowing to drive away every new nanny. Yet Nora harbors a secret: she can create clones. With this power, she repeatedly defuses the children’s pranks and gradually earns their trust. She also develops subtle emotional ties with Elias, the manor’s master and a single father hiding his deep‑sea lineage. As outside forces track down Nora’s secret, this seemingly bizarre cross‑species family becomes each other’s warmest refuge.
