During the military training in the first year of high school, Xu Xingmian fell in love with Song Chengan at first sight. This love was hidden in her eyes secretly watching him standing in the military posture, and also hidden in her panic when she was occasionally helped by him. She mustered up the courage to confide her concerns to Shen Nian, her classmate she had just met, and Shen Nian, as an "old acquaintance" who had been in the same class with Song Chengan from elementary school to high school, readily agreed to help her and create opportunities for the two of them to get along.
At the same time, Song Yanzhou bumped into Shen Nian by chance, fell in love with this cheerful and lively girl, and silently followed her every move. The youth of the four people are intertwined: Xu Xingmian slowly approaches Song Chengan with the help of Shen Nian. While Shen Nian is running for his friend's secret love, he is quietly affected by Song Yanzhou's gentle gaze, while Song Chengan always feels a vague sense of distance from this warm approach.
As the youthful good feelings gradually fermented, the past bonds and secret thoughts began to emerge. This youth story started by "Assist" ultimately failed to withstand the grinding reality and the misalignment of fate, leaving only a regretful ending, which became an old trace that could not be fulfilled in the memory.
Purpose: "True love is not afraid of time and separation, and is a firm choice across mountains and seas." The core is Song Chengan's behavior of sticking to love for the rest of his life after Xu Xingmian was terminally ill and finally passed away, interpreting the weight of "true love". His perseverance breaks the limitation of "parting is the end of love" and proves that when a person truly loves you, obstacles such as illness, life and death cannot erase this feeling - this love is not only Xu Xingmian's confidence when facing difficulties, but also the most touching annotation of "love": those who are firmly chosen will never have to worry about being abandoned due to changes in circumstances.
