On the first day of the first year of high school, a boy (Lin Jing), a transfer student from Shandong, who was superior in both clothing and height, made the girl (Li Xiaoran) fall in love at first sight.
From then on, due to their height, Lin Jing and Li Xiaoran became roommates. Li Xiaoran's grades were good except for science, and Lin Jing's grades were very good and he was the top two in the class. They were originally roommates who did not talk to each other, because Li Xiaoran and Lin Jing's brother (Jiang Ke) had been good friends in the same class for six years and had a harmonious relationship. Gradually, Lin Jing and Li Xiaoran talked about everything and started to fight each other as soon as they met.
But behind the scenes, Li Xiaoran silently likes Lin Jing, but Lin Jing's thoughts towards Li Xiaoran are unpredictable.
What will happen to them in this high school environment?
Intention: If we take different paths in the future, remember the good things and see you again by fate.
