Three-and-a-half-year-old Su Nuonuo was locked in a small dark room and abused by her grandmother's family after her mother passed away. She accidentally discovered the photos and diary left by her mother and learned that her biological father was the top boss Lu Jinghan. She hugged her little schoolbag, ran out secretly, rushed all the way to the Lu Group, and in front of all the company's executives, hugged Lu Jinghan's thigh and called her daddy. At first, Lu Jinghan just thought it was a pity. He disliked this sudden little trouble and just wanted to send her away quickly. But the DNA test results put a damper on the relationship between father and daughter. Nuo Nuo's soft, cute, sensible, sweet and considerate words gradually melted his heart that had been frozen for many years. Lu Jinghan gradually became more and more popular, from "Don't touch me, I'm dirty" to "No one can bully my daughter", turning into a well-known doting girl on the Internet. Nuo Nuo relied on this thickest golden thigh to beat her best relative, the vicious White Lotus, who had bullied her one by one, and was pampered like a little princess in kindergarten. At the same time, she used her gentleness to cure Lu Jinghan's lack of love and insomnia in childhood. The father and daughter ran in both directions, and Lu Jinghan gave Nuo Nuo a happy family. Nuo Nuo became Lu Jinghan's most precious weakness and armor in his life. In the end, the whole family loved each other, and there was no abuse in the whole process, and he was a happy ending.
