Miao border girl Tuan Tuan, seemingly an ignorant cute toddler, actually harbors a mysterious system. To awaken her sleeping mother, she carried her small cloth bag and barged into high society alone, standing before cold-faced CEO Fu Jingchen with a love letter and a paternity test. In one 'reverse parenting' family task after another, she melted the iron heart of her iceberg father. When the truth of the amnesia is uncovered, she transforms into a little matchmaker, leading her parents to rewalk the path of love, and ultimately piecing back together a shattered home. It turns out what she brought is not just witchcraft, but the lost and recovered light of this home.
