Four Beast Lords Fought over a Rabbit Healer

After a broken engagement, "useless" rabbit-shifter Chloe awakens a Beast God Care System and opens a kindergarten. She takes in a defective white tiger cub and other young beasts, unaware they are actually degenerated, top-tier beast lords. As jealous rivals and the Royal Healing Institute plot to destroy her, Chloe uses her S-class soothing powers to heal the lords. The powerful men regain their true forms, fiercely protecting her and vying for her love.
