On the way back to the rental house, Xia Wei found a dying two-month-old Labrador puppy next to the garbage station - it was tortured by parvovirus and canine distemper, and was soaked all over and its eyes were blurry. At that moment, she took the puppy home regardless of the fact that she had just lost her job and was in arrears with her rent. She named it "Lucky" - because meeting is luck and having it is luck.
From then on, one person and one dog depended on each other in the cold and hot city of Beijing. The sudden outbreak of the epidemic, the lockdown and quarantine, the collapse of the early childhood education industry, and the shattering of the dream of Beidiao... In the darkest moment, Lucky supported Xia Wei with unconditional loyalty and vitality. After the lockdown was lifted, she fled Beijing, Shanghai and Guangzhou with Lucky and returned to her hometown of Nanchang. She started by setting up a stall in the night market, telling heart-warming stories of "people and pets" with handmade jewelry, and founded the "Hello Lucky Cultural and Creative Studio". On the way to start a business, she meets Lin Song, a dog trainer who is calm and rational but deeply gentle - he understands Lucky's every move and the stubbornness in Xia Wei's eyes.
This is not only a story about a girl and a dog redeeming each other, but also a story about faith, rebirth and love.
