简介：Two-and-a-half-year-old Ruby stumbles into the world of Ethan, a mafia godfather, claiming to be his "puppy born from him". Guided by the system sprite Sparky, she carries out a rescue mission. Greedy for snacks and naive, she relies on her puppy instincts to accidentally uncover plots involving venomous snakes, snipers, poisoned coffee, bombs and kidnappings time and again, protecting Ethan and his brother Lucas, who has been reborn to seek revenge. The cold-blooded godfather and his tsundere brother are gradually softened by her innocence, while the villains Victor and Elena are ultimately defeated. After Sparky runs out of energy and vanishes, Ruby turns into a real human girl, loses her past-life memories, and becomes the little princess doted on by the whole family.
