Pei Youyou, the true daughter who can understand the thoughts of animals, returns to the Pei family. She originally wanted to rely on the support of her older brothers to build a wild animal protection zone for her animal little friends, and incidentally be a happy foodie. Who would have known that the family conditions are constantly troubled: the eldest brother is deeply plagued by insomnia, the second brother's career encounters a bottleneck, and the third brother has limited mobility and needs someone to take care of him. Pei Youyou takes her animal intelligence network on a heartwarming strike, on one hand using a unique way to accompany and heal her brothers, and on the other hand following the clues to figure out the truth behind the strange occurrences in the family, which turns out to be someone plotting misconduct in secret. In the end, the truth comes to light and the crisis is resolved. Pei Youyou not only guards the warm home, but also successfully builds the wild animal protection zone as she wished.
