The boss invites a married couple to a hot spring inn, and the wife reluctantly accompanies him. Upon arrival, she is shocked by an unexpected situation: the boss's sycophantic senior colleague and a rumored mistress-like female employee are present, creating an atmosphere far from a typical married couple's outing. Urged to change into a yukata, the wife returns to the gathering after a brief discussion. As the party progresses, the young female employee becomes extremely drunk and collapses. Seeing the boss looking lonely, the wife begins to attend to him with concern, unwittingly drawing herself into an intimate situation.
