Xiaoxiao exchanged identities with her god-sister Huanhuan, but this exchange made Xiaoxiao's biological parents mistakenly believe that Huanhuan was their biological daughter, and regarded their biological daughter as their adopted daughter. Her biological brother also thought so. From then on, he misunderstood Xiaoxiao, beat Xiaoxiao, and sent Xiaoxiao to a correctional center. After Xiaoxiao came out, his adoptive father was the richest man in the world and punished those who bullied Xiaoxiao in the correctional center. The adoptive father was very kind to Xiaoxiao. After Xiaoxiao returned home, she wanted to see her grandma, but her biological parents kept making mistakes again and again, and Xiaoxiao was lost forever.
