Su Nianwei's high school sophomore life was disrupted by a class list - she and Jiang Yu, a popular figure on campus, became front and back. He was as dazzling as the midsummer sun, but she was used to hiding in the shadow of words. When an unexpected collision in the basketball game opened up the ambiguity, the "fake couple" agreement at the cultural festival tied the two together.
He sent her home under the guise of an agreement, and the moment their shoulders touched under the umbrella, she heard her deafening heartbeat; she quietly mended the holes in his socks, and the stitches were filled with secrets that she dared not tell. The bell rang for the senior year of high school, and the admiration of the transfer student Xu Zhe made Jiang Yu jealous. The pressure of studies and dreams caused constant friction between the two who were in love for the first time.
Under the night sky of the fireworks display, Jiang Yu finally grabbed her hand: "Su Nianwei, I can't keep up the fake show... Because I have already been sincere to you." In the midsummer when the admission notice arrived, they stood with their fingers clasped in the crowd at the graduation ceremony. The shadows of the sycamore trees swayed, and the boy carved a promise into her palm: "From the classroom to the future, my destination will always be you."
