We know that Zuo Zhiyuan is a young man who is proud, arrogant, lonely and indifferent.
But he is also a child, a very simple child, a child who does not understand love and worldly affairs.
He got close to his math teacher Xiao Chen, grew up abnormally in a quick love, exhausted his energy in the impulsive and reckless complex relationship of teenagers, and struggled in the indifferent family relationship without finding a way out.
This is a story about growing up. It is not sunny or happy. Because growth is painful, like the pain of bone growth, if you can't get rid of it, you must experience it.
