Quick! Grab Little Sis Before She Gets into Trouble Again!

A modern family comedy blending laugh-out-loud everyday antics, heartwarming healing, and a touch of mystery. Three-year-old Su Nuannuan looks like a sweet, angelic little dumpling, harmless as can be. But inside, she's the ultimate BOSS, equipped with "human wrecking-ball skills" and an "aura of troublemaking powerful enough to bend causality." Her daily routine is to turn her family's life, and even the whole neighborhood's, upside down all by herself: planting succulents in Dad's limited-edition sneakers, folding her big brother's graduation thesis into paper airplanes, and livestreaming "ink-splash art" during Mom's most important client meeting... Yet whenever the whole family is in chaos and their blood pressure is through the roof, the disasters Nuannuan causes by accident somehow end up exposing hidden secrets, mending broken relationships, and even averting a major crisis. Then one day, she gets into trouble with a business rival who has come to investigate in secret. A shocking conspiracy that could determine the family's very survival is accidentally brought to light by this three-year-old... Only then does the whole family realize that their little troublemaker may be the most extraordinary lucky star Heaven sent to protect them.
