On the cold winter day just after the Chinese New Year, Su Zhiqiao, a senior in high school who was preparing for the college entrance examination, met Ji Yanyan, who was five years older and was responsible for watch repair, at the watch counter of a shopping mall.
He has a calm and restrained personality. He spends all his time in the company of precision watches and clocks, and has a sense of maturity and alienation. The girl fell in love at first sight and started to take the initiative to approach. She often used the excuse of adjusting and looking at the watch to frequent the store and boldly express her feelings.
The male protagonist is sober and rational, fully aware of the huge age gap between the two, and is even more afraid that this affection will delay her from sprinting for the college entrance examination, so he has been deliberately keeping the distance and politely rejecting the girl's enthusiastic advances.
The pendulum swings from winter to midsummer, but the girl's persistence never wavers. He was gradually moved by this pure enthusiasm, put down his worries, and waited patiently for her to pass the college entrance examination and fade away, so that the encounter that started in the winter at the mall could slowly develop into a stable love despite the age difference.
