When Su Mengmeng was four years old, she met Lin Yuxuan under the old locust tree. He gave her a toffee and became her most reliable "Brother Xuan" in her childhood - holding an umbrella for her on rainy days, driving away bullies for her, and calling her "as cute as a bunny" when she lost a tooth.
From kindergarten to high school, their trajectories are closely intertwined: it is the homework books quietly passed between the classmates in elementary school, the elongated shadows side by side under the street lights in junior high school, and the deafening "I like you" in the high school basketball game. The provocations of transfer students, the awkwardness of adolescence, and the pressure of entering higher education failed to break the bond between this pair of childhood sweethearts.
When the university was in a different place, he traveled thousands of miles just to give her a surprise; on the day of graduation defense, she looked into his eyes in the audience to regain her courage; at the wedding, he said with red eyes: "From the school uniform to the wedding dress, you are my only obsession in this life."
There is no vigorous and vigorous love, only a long-lasting love. He remembered all her little habits and she treasured every little gift he gave her. From his first encounter under the locust tree to his old age on a rocking chair, Lin Yuxuan spent his life proving that some heartbeats cannot be hidden from the age of four; some people, once they are put in their hearts, they will last a lifetime.
