Ten years after divorcing her ex-husband, the female protagonist runs a tea house alone, living a stable and calm life with poise. Unexpectedly, her ex-husband brings his current wife to provoke her, deliberately flaunting their lifestyle, mocking and putting her down with words, and even delivering an anniversary invitation to publicly humiliate her for living alone. To defend her dignity and fight back against secular prejudices, the female protagonist resolves to find a companion with a composed demeanor to attend the banquet, using a dignified posture to prove that a woman's independent and poised life never depends on others.
