You Are My Whole World

To raise money for her mother Su Wan's ALS surgery, little Xiaobao makes a wish at the wishing pool and then tries to refund the zoo's annual pass — only to be challenged by the ticket aunt. In the argument, Xiaobao's white hair and the surgery money she carries are exposed; she shows her bone-marrow donation volunteer certificate to prove she donated marrow to save her mother, which turned her hair white. Deeply moved, the zoo director rallies everyone to scoop coins from the wishing pool and launches a donation drive. Gu Lan, the second daughter of the Gu family, also donates — but accidentally spots the Eight-Treasure Compass around Xiaobao's neck, a Gu family heirloom. She suspects Xiaobao is the daughter of her younger brother Gu Jingzhou. At this time, Gu Jingzhou is still refusing the family-arranged engagement with Zhao Mingyu, eldest daughter of the Zhao family, haunted by the past of being "abandoned" by Su Wan. Gu Lan brings Xiaobao's hair for a paternity test, and the result confirms the two are father and daughter. But when Xiaobao learns the surgery will cost a million, she falls into despair again. While pushing Su Wan across the street, she clashes with Zhao Yiming, the Zhao family's young master — arrogant and domineering, he not only insults Xiaobao but kicks over Su Wan's wheelchair and snatches the life-saving money. When Gu Jingzhou learns of his daughter's whereabouts, he mobilizes helicopters and drones to search the whole city, arriving just in time to rescue Xiaobao and Su Wan from Zhao Yiming, who is threatening them with a baseball bat. After Xiaobao faints and is taken to the hospital, the Gu family is shocked by her white hair. Gu Lan and Old Madam Gu initially misunderstand that Su Wan has been using Xiaobao, but Xiaobao fiercely defends her mother, recounting the hardships of Su Wan raising her alone. After Su Wan wakes from surgery, Gu Jingzhou, now aware of Xiaobao's years of marrow donations, produces a custody agreement for Su Wan to sign. Su Wan asks only for one last trip to the amusement park with Xiaobao. Later, while working at the Emperor Hotel, Su Wan overhears Zhao Yiming and Zhao Mingyu plotting to poison Xiaobao with tainted chocolate. She rushes to stop them but is doubted, and eats the chocolate herself to prove her innocence. Gu Jingzhou finally sees Zhao Mingyu's true colors, and at the engagement banquet, he follows Xiaobao to rescue Su Wan, who has been kidnapped by Zhao Yiming. The truth comes out: Zhao Mingyu and her brother's crimes of poisoning and kidnapping are exposed, they're handed over to the police, and the Zhao family collapses under its own financial ruin. Old Madam Gu and Gu Lan apologize to Su Wan and Xiaobao, and Gu Jingzhou produces the Eight-Treasure Compass, officially reclaiming Su Wan and Xiaobao. In the end, Xiaobao gets the schoolbag she'd been hoping for, and the family of three, together with the Gu family, finally reunite and begin a happy life.
