In the summer of the second year of high school, Pei Zhiyu, a transfer student, and Jiang Lin, a vicious school bully, became enemies over a quarrel and started to fight each other when they met.
But in the days of tit-for-tat, love quietly grew, and the two came together naturally.
In the third year of being together, Pei Zhiyu was diagnosed with bone cancer. In order not to drag Jiang Lin down, he hid everything and broke up alone.
A few months later, a phone call from the hospital shattered Jiang Lin's fantasy - Pei Zhiyu had passed away.
The diary that hid all the secrets made him finally understand that breaking up was not about lack of love, but about too much love.
In the end, Jiang Lin walked to the shore where they had watched the sea together, and made a date that they would never be separated from again.
Intention: Study hard and make progress every day
