The first encounter in the back seat of the school bus caused a misunderstanding between the socially fearful Lin Yueyu and the enthusiastic Lu Zhixing. The wrong notes delivered in the library, returning home at night on the same road, and the trivial campus daily life, they became the most special existence in each other's youth. When she graduated, Lin Yueyu hid her secret feelings in her diary and wrote only one sentence: "The future is bright."
Many years later, the two people, who were already working hard in the workplace, met again in the same city. Lu Zhixing accidentally opened the yellowed diary, and was shocked to realize that the time they spent together day and night contained the unspoken attachment of his senior. From school to the workplace, misunderstandings and misses once stood between the two, but as adults, they learned to face their hearts.
When Lin Yueyu was on the verge of collapse under the pressure of the workplace, it was Lu Zhixing who stayed with him all night; when Lu Zhixing encountered setbacks in his business, Lin Yueyu silently provided support. Those unspoken thoughts in youth have turned into a firm two-way rush. From young best friends to mature lovers, their story is a gentle guardianship across the years, and it is also the most precious romance in the adult world.
