On a university campus during the rainy season, the male protagonist meets a girl in a literary club who is insecure and is used to closing herself off. The girl sets up three questions about her best friend to screen out the newcomers. The male protagonist successfully passed the test by paying careful attention to every detail. From then on, he spent time in the club working on manuscripts, walking under an umbrella on rainy days, and spending time together in the library. Warm milk, low-sugar mung bean paste, and silent companionship slowly melted away her inner layers of defense. The two developed a subtle affection in the continuous rain, but because the heroine was afraid of separation and was entangled in the future, they always stopped at being with each other tenderly. When it was sunny after graduation, the male protagonist quietly deleted all contact information, and the two separated, sealing their young heart in the humid rainy season youth.
Purpose: To use the continuous plum rain as a metaphor for the character's inner sensitive depression, and to describe a restrained and pure campus secret love. It explores the interpersonal fortification caused by native insecurity, and the confusion that young people face about their future and relationships. It explains that the best encounters may not last forever. Keeping tenderness in memories and letting go with dignity is also a kind of fulfillment, highlighting the reserved, regretful and complete love in youth.
