The female lead accidentally encounters the soft and cute cub Zaizai, who clings to her and calls her mom, extremely adorable. The dean of Saint Lanster Academy comes looking for her, just as Caesar, a powerhouse of the Azure Dragon clan at the pinnacle of the interstellar pyramid, appears. Caesar, who has severe germophobia and detests being touched by others, does not repel the cub's closeness. Observing the cub's blonde hair, dragon horns, and other features, everyone suspects he is Caesar's child. According to the Federal Cub Protection Law, a lineage test is required. Deep inside, Caesar also feels an inexplicable blood bond, agrees to cooperate with the inspection, and demands an explanation of the background, but the female lead is completely baffled and has no idea where the cub came from.
