When Lin Zhiwan was seventeen, she fell in love with Shen Yanzhou.
Shen Yanzhou is the number one in his grade. He is cold, restrained and silent, like a person who always stands in the light. Lin Zhiwan is a girl in an ordinary class, with good grades and an ordinary family background. She is used to hiding all her emotions behind her smile.
She thought she was just watching him from a distance.
But later she learned that Shen Yanzhou had secretly looked at her back during countless evening self-study sessions.
In his senior year of high school, Shen Yanzhou's family suddenly collapsed. His father went bankrupt and his mother fell ill. The once proud young man was forced to grow up overnight. He began to alienate everyone and pushed Lin Zhiwan away again and again.
Lin Zhiwan thought he hated her.
Shen Yanzhou thought that leaving would protect her.
On the night after the college entrance examination, Lin Zhiwan finally confessed to her love.
Shen Yanzhou only said: "Don't wait for me."
In the following fifteen years, they approached and retreated again and again, separated by cities, identities, responsibilities, illnesses and fates.
The friends around them also went to different lives: some married into rich families but lost their freedom, some failed to start a business and fell to the bottom, some became teachers to preserve their youth, and some left their hometowns and were never heard from again.
Many years later, Lin Zhiwan returned to his alma mater as a substitute teacher.
She found the letter left by Shen Yanzhou in her old school desk, and then she realized that during that youth, they had never truly loved each other.
It's just that I didn't dare to say it when I was a teenager, and I couldn't say it as an adult. In the end, I didn't even have the chance to say it.
Concept: Youth is not only about love, nor is it only about regrets. It is the first time a person sees the complexity of the world, the first time he understands that love cannot solve all problems, and the first time he understands that some people may not be able to walk together even if they love each other.
