Lin Wan, a gentle and tough book editor, and Shen Zhiyuan, a cold and affectionate technology upstart, were once the most dazzling lovers on the high school campus. Due to a carefully designed misunderstanding, the two separated without saying goodbye for ten years. Ten years later, Lin Wan returned to China to take over the family bookstore, but reunited with Shen Zhiyuan at an industry reception. He is no longer the taciturn young man back then, but a technology giant with capital in hand, and a "fiancée" with outstanding temperament standing next to him. When an old love reunites and there are many misunderstandings, can the two get rid of the fog and find the starlight that belongs to each other?
