Jiang Mo's memories are always related to rain, but in fact Linfan is a place of "always sunny and occasionally rainy", just like Jiang Mo's youth, also "always sunny and occasionally rainy", such as Zhu Chunxin's sincere friendship, Chen Yuetian's care as a deskmate, and Pei Yu's unknown love.
When she was with Zhu Chunxin, Jiang Mo was arrogant. She was holding an umbrella, so she couldn't see Zhu Chunxin's attachment and care. Later, in the story with Chen Yuetian, Jiang Mo was supposed to be the one caught in the rain, but Pei Yu secretly held an umbrella for her.
The "sunny" in youth is obscured by pride. The "rain" will only stop when Jiang Mo puts down her umbrella. The "rain" of adulthood is the numbness of life, but when she returned to Linfan, Jiang Mo's clock hand finally turned back from tomorrow to the present, helping her see clearly the truth about those "sunny days" in her youth.
Tomorrow will never come, it is far away and unreachable, so the present is precious; pride is often a shackle, and you will not know until the umbrella falls, so only those who have a heart are.
