Lin Xiaoxiao, a socially anxious homebody who has failed the civil service exam three times, is pushed by her mother into a community job as a garbage-sorting supervisor.

With a pot of mint tea and a sincere heart, she turns their hostility into understanding. From being insulted until she cries to receiving a commendation banner, from wanting to run away to becoming someone others rely on, she discovers her own brilliance in the most unassuming job.
