In the second semester of his second year of high school, Shen Ye was transferred to Class 1 of his third year of high school and became Lin Xingwan's new classmate. Two people wearing different masks, under the pressure of the countdown to the college entrance examination, went from silent confrontation to quietly approaching. Xingwan discovered the gentleness beneath Shen Ye's cold appearance, and Shen Ye saw through the scars behind Xingwan's sunshine. They shared the same pair of headphones in the late-night study room and watched the same starry sky on the rooftop. However, their budding relationship came to an abrupt end due to a carefully designed misunderstanding, a wishing bottle that could not be delivered, and a silent farewell on the eve of the college entrance examination.
Six years later, on a winter night in Beijing, Shen Ye, now an architect, met Xingwan at the subway station who was returning to his alma mater to give a speech. Time passes and the starry sky remains the same. Can those unsaid words still be recovered?
