Little milk tot Zhizhi accidentally activates the villain redemption system. By coincidence, she meets Ji Shiye, who has encountered life setbacks, and invites him in a milk-soft voice to become her family. Meeting multiple dejected bigshots along the way, Zhizhi picks them all up as family without hesitation, warming them in their low points with her pure kindness. The Lu family members see their true hearts, filled with regret. The bigshots transform into child-guarding maniacs one after another, guarding Zhizhi all the way, jointly resolving various crises, and slowly building their warm little home together in the days accompanying each other; the sweet and cute pet warmth goes online.
