In that rainy school season, Lin Zhi, a girl from Jiangnan, met Shen Juan, who was full of light. A black umbrella and an encounter under a sycamore tree made the souls of two worlds unexpectedly meet. She is an ordinary student trying to adapt to life in a big city, and he is an artistic talent who bears the expectations of his family. They think that love can transcend everything, but they don't know that class gaps, carefully designed misunderstandings, and young self-esteem are quietly weaving a web of separation.
Five years later, Lin Zhi saw the painting titled "Gardenia" at an art exhibition in a foreign country - it freezes her looking back in the rain when they first met. She finally understood that all of Shen Juan's scenery began and ended with that unkept moment. Just like the monsoon passing by the phoenix tree year after year, they had loved each other so hard, but in the end they could only become the most profound miss in each other's lives.
