Yvette Sullivan, an orphan of Prince An's Manor, is born with an innate ability to communicate with animals. On his deathbed, her Master reveals her true background and instructs her to leave the mountain to search for her four long-lost elder brothers. The five siblings recognize each other through their matching Kinship Bracelets, work together to uncover the truth behind the family massacre ten years prior, and discover that the mastermind behind the tragedy is none other than the reigning emperor. They outwit powerful court officials, gather irrefutable evidence, ally with the virtuous prince, and finally successfully force the emperor to clear their family's name, before each goes on to pursue their ideal lives.
