The willow tree symbolizes retention and blessing, just like the love Su Shiyu couldn't get, lovesickness and longing to return, just like her nine years of expectation and full joy finally came to nothing.
The 18-year-old girl still died under her favorite willow tree.
Although the down-and-out girl has no courage, she still wants to try her best to catch the light.
Su Shiyu always thought that the fog that cannot be grasped by light will eventually dissipate, and people always have to say goodbye to things that they cannot grasp. The person I like has light, light but not shining, and light is the same as dust.
In that time of relying on each other, the young man finally used his dream as a horse and headed for the distance.
