Lin Xiaoxing, who is a "community animal" after graduation, works part-time as a night shift convenience store clerk to collect rent. Every night, he meets the mysterious customer Gu Yanshen over a piece of oden. He is a wealthy group president, but he is intoxicated by her optimism and tenacity, and quietly listens to her workplace worries. When she was bullied and fell into a low point, he turned into an invisible knight and silently supported her. From the warm company at the convenience store late at night to walking side by side in the office building, the two crossed the identity gap and guarded the long-lasting healing love in the bustling city.
