Lu Ze, a 24-year-old graduate from a prestigious university, pursues Zhang Guifen, a 44-year-old laid-off female worker. The widow Zhang Guifen and her 22-year-old daughter Luo Lan were Lu Ze's primary school substitute teacher. From Lu Ze's perspective, when he was in elementary school, he was a poor student who was laughed at by the whole class and was ignored by the teacher. Only Zhang Guifen patiently helped him sort out the wrong question papers, marked the key points with a red pen, and advanced his tuition fees, saying, "You are good at studying." This sentence supported him to get admitted to a prestigious university. Now that he has become famous, he just wants to repay it with his whole life.
