One rainy night during the plum rains, 20-year-old university student Luo He encounters an “unexpected guest” who will change his ordinary life: Bai Xixi. Barely 1.4 meters tall and weighing as much as a child of eight or nine, the girl has amber eyes and an exceptionally delicate face. She looks like a 14-year-old who needs looking after, but in truth she is a fox spirit who has lived for 182 years.
Unable to maintain a stable human form, Bai Xixi was branded an “oddity” and driven away by her own kind. Clutching a threadbare stuffed fox, she knocks on Luo He’s door in a sorry state. From accidentally revealing her fluffy white fox tail to finally confessing, “I’m a fox spirit,” she takes Luo He from shock to sympathy, and eventually finds a home with him. Though she looks young, her eyes hold a century of loneliness.
From then on, life in the rental apartment grows lively and heartwarming. Luo He teaches Bai Xixi about escalators, hamburgers, and fries in the human world, and helps her pick out pink dresses and a brush for her tail. In turn, Bai Xixi warms Luo He with a fox spirit’s simple sincerity: she gives him her soft-boiled egg, brings him a “good luck stone” she found in the mountains, and hums little off-key tunes as she brushes her tail.
But living with a fox spirit comes with its share of “little troubles”: accidentally using her magic to wilt the pothos, having to hide her tail whenever it can’t help poking out, and being so curious about everything in human society that she’s like a “little question machine.” Yet these clumsy, adorable moments are what bring the two lonely souls closer. As Luo He cares for Bai Xixi, he finds warmth in his life, and Bai Xixi finally finds a “home” with him, where she no longer has to wander.
