"Maybe I should go into research." That's what I thought back in college. But under the pressures of real life, I gave up on academic research. With the help of my mentor, I started teaching at an ordinary high school. There, I met many friendly colleagues and kept in touch with my college friends. I used to think that my ordinary life would just go on like this, but everything began to change when I arrived at 'Fenghua School.'

Su Heling: The daughter of the owner of Qimo Real Estate, she studies at the locally renowned elite high school 'Fenghua School.' However, due to the decline of the real estate industry and resulting financial difficulties, although she attends an elite high school, she seems to face the possibility of transferring to another school. After Xu Bu arrives at 'Fenghua,' she becomes a student in Xu Bu's temporary class. Su Heling's life also seems to be encountering a new turning point.

Zhang Anyi: An English teacher in the same class as Xu Bu, and they share the same office. She started working a year earlier than Xu Bu and is the teacher with the closest relationship to him, often having meals together. She has a poor tolerance for alcohol, but when in high spirits, she always forces herself to drink, eventually being sent home by other female colleagues. She dresses elegantly, teaches gently, and is extremely popular among students.

Old Wei: Xu Bu's college roommate, from a coastal province known for civil service exams. He repeated two years of high school and is two years older than Xu Bu. After graduation, he chose to stay local and opened a Chinese fast-food restaurant, specializing in cold noodles and cold skin noodles. Although he is not yet thirty, he looks like he has already entered middle age. He still keeps in close contact with Xu Bu and often asks for suggestions on new products in his store.

Han Ji: A student of 'Fenghua School', who prides himself on having realized the truths of the world, is a teenager full of typical adolescent arrogance. His father seems to be a school administrator, so he usually doesn’t wear a school uniform. He looks down on ordinary students who quietly do their work, as well as on Xu Bu, who comes from an ordinary high school, considering himself the center of the world. At the same time, he seems to have a mysterious obsession with Su and Ling.
