A free-spirited senior office lady often misses the last train and barges into her junior coworker’s home instead of paying for a hotel. She mocks him for being bad at work, bosses him around, and even brings her boyfriend over to flirt in front of the lonely man. One night she arrives completely drunk and mistakes the coworker she bullies for her boyfriend. Showing a feminine side he has never seen, she clings to him and begins fondling his crotch. Her mistake may finally give him the perfect chance to turn the tables.
