Jiafu (Jaycee Chan) was born in a grassroots family. His father (Eric Tsang) is a minibus driver and his mother (Teresa Mo) is a restaurant receptionist. Although he was born in a humble family, he enjoyed the warmth of his family. He went to a famous girls' school with his classmates and accidentally saw Ruonan (Fiona Sit). He even pretended to be a student from a famous school to socialize at the girls' school. Ruonan's father (Anthony Wong) is a lawyer and her mother (Annie Yu) is a public welfare activist. She has always been strict with Ruonan and rarely stayed with her daughter. When Ruonan met the active Jiafu, she was quickly attracted to him. On the night of Ruonan's 18th birthday, the two of them went camping in the suburbs and ate the forbidden fruit. After Ruonan learned that she was pregnant, she discussed with Jiafu to abort the child. Seeing those horrible tools and having a big fight with her family, she decided to hide in her friend's ancestral house until the child was born. After living alone, Jiafu realized that it was not easy to support a family, and the two began to have differences. Jiafu's parents finally found the two people, but if the father wants to sue Jiafu for raping an underage girl, will he show mercy when looking at his grandson who was born prematurely?
