An An and her ex-boyfriend "cleared accounts over the cat", taking the cat "Jin Bao Zi" to start a new life. The very first thing An An did after moving to a new home with the cat was to take it for neutering! Jin Bao Zi begins "revenge", knocking over water cups, parkour, stepping on the keyboard, but every mischief turns into a divine assist, scaring away a bizarre blind-date man, driving away the entangling ex, and saving a work crisis. And the veterinarian Wen Xin who neutered Jin Bao Zi turns out to be An An's neighbor, a ludicrous human-cat game of wits begins, and Jin Bao Zi and Wen Xin both end up becoming An An's protectors!
