High school was a footnote to the youth of Chen Ye, Jiang Sui, Li Jiang and Lin Xiaoyu. At that time, they sat side by side in the sunshine, thinking that friendship would be like the writing on the school uniform, always clear and never fade.
As time goes by, time pushes them to different life crossings. Chen Ye and Jiang Sui passed through many tests, changed their school uniforms into wedding dresses, held each other's hands with the blessings of their friends, and let their love settle into a long-lasting marriage; Li Jiang and Xu Jiazheng were in a passionate love, with their hearts hidden in every glance, and their longing for the future in every hug, extending the throbbing of youth into a warm present.
However, Shi Lingqiu and Lin Xiaoyu failed to withstand the twists of fate. An unexpected separation made their story stop at the most regrettable moment forever, leaving Shi Lingqiu with memories and repeatedly salvaging pieces about Lin Xiaoyu in the days to come. Three pairs of lovers, three endings, but they are always entangled with the friendship that started in high school and never really dissipated, writing chapters about love, regret and companionship in time.
