Three-year-old soft and cute little darling Maomao moves into the Warlord's mansion with her mother. With her innocent and lovely personality, she quickly captures the hearts of the entire household and heals the depressed fourth young master who was disabled due to an accident with her pure innocence. Seeming to bring her own good luck, she always senses danger in advance through intuition, repeatedly helping her family escape disasters. From the elders in the mansion to the young masters and socialites outside, everyone holds her in the palm of their hand to pamper her, staging one warm and humorous "pet-competing" daily life after another, while the little darling also grows up happily amidst boundless love.
