In a modern city where information is exploding, independent bookstore manager Shen Yan uses encrypted bookshelf sorting to isolate ineffective social interactions, while emergency doctor Lu relies on precise social templates to cover up emotional isolation - two people who use different methods of "self-protection" intersect due to an unexpected encounter in a rainstorm. Shen Yan's social fear hides the fear of "being seen through", and Lu Ze's gentleness is a deliberate avoidance of emotional connection. However, an injured cat, a misunderstood video, and the secret of an out-of-print book are like stones thrown into a calm lake, forcing them to face "accidents" beyond each other's logic. When Shen Yan's bookshelf order was broken by Lu Ze's reasoning, and when Lu Ze's social template failed in Shen Yan's silence, the two people who were accustomed to building walls with reason finally saw clearly in the collision: the so-called "self" is never an island isolated from the world, but the tenderness that slowly grows in the cracks in understanding each other.
Purpose: To explore the emotional defense mechanisms and desire for connection of modern urbanites, with the "softness under the rational shell" as the core, to show how two independent individuals learn to accept each other's "imperfections" while maintaining their own sharpness, and finally understand that true understanding is never about seeing through the other person's logic, but respecting his unique way of getting along with the world.
