Reira is a housewife married to the president of a small company, living with him alone. One day, she receives a call from her husband asking her to deliver a forgotten item, and rushes out of the house without makeup. However, inside the train, she's overwhelmed by unexpected crowds, visibly shocked and flustered. Conscious of the cold stares from fellow passengers, Reira hurriedly begins applying makeup inside the car—drawing attention for her breach of etiquette. Unnoticed, a sinister hand creeps closer. She can't possibly arrive at her husband's company looking like this. Meanwhile, one of her husband's employees secretly watches her predicament. An unexpected incident suddenly turns Reira's ordinary life upside down.
