The abandoned "little broom star" Nuan Nuan was unexpectedly adopted by a top wealthy family. In her daily life as a "group pet", her special ability (absorbing bad luck) was misunderstood as a "koi constitution", attracting covetous attention from all parties. When the truth was revealed and she was in danger of being exploited, the Shen family did their best to protect her. In the end, Nuannuan used love as the power to resolve her own curse, feed her family back, expose her biological father's conspiracy, and become a "little lucky star" truly cherished by the world.
