Born as the daughter of a black leopard and a snow leopard shapeshifter, seven-year-old Tiel spends her childhood suffering under the abuse of her cruel family. Desperate to escape their mistreatment, she runs away in search of the father she has never met, hoping only to find a safe place where she can finally live without fear.

What Tiel does not expect is that her father turns out to be Duke Asterian, a powerful and feared noble known throughout the land. Rather than rejecting her, the duke welcomes his long-lost daughter with overwhelming affection and becomes determined to give her the warm, loving family she has always been denied. Surrounded by new people who genuinely care for her, Tiel slowly begins to experience happiness and comfort for the first time in her life.

However, peace does not last long. Dangerous enemies and dark forces soon emerge, threatening to tear her away from the family she has finally found. Determined not to lose the people she loves again, Tiel resolves to fight with everything she has to protect her new home and the precious bonds she has gained.
