For the past three months, Kojima has been experiencing a sexless marriage. Sensing her husband might be cheating, she pretended to clean his study and searched for clues—eventually finding a single business card. The card bore the name of a private SM club.

Learning this, Kojima felt heartbroken, wondering if her husband found more pleasure in the club's activities than in their marital intimacy. Her melancholy words revealed deep disappointment and insecurity.
