From elementary school to high school, Shen Mo's grades were always higher than Lin Yi's. Number one in grade, champion of competitions, role model in the teacher's mouth - he was her arch-enemy, the one she vowed to crush under her feet.
But she didn't know that this "competition" that lasted for eight years was his long-planned approach from the beginning.
A notebook that records more than two thousand days and nights, and a confession that "it started in the fifth grade of elementary school" reveal the truth about all "coincidences" - there are no chance encounters, only premeditation; there are no old enemies, only secret love.
This is a two-way journey from competition to love between two top students. It is a story of one person trying his best to get close to the other over a long period of time, and the other just happens to be walking towards him.
Do you think they are old enemies? In fact, he had planned it for a long time.
Concept: When the Bingshan top student who "only studies in his heart" meets his childhood rival who is "secretly evil", during the three years of high school, she thought he was competing, and he thought it was time for her to find out.
