The Barrelmaker Brimful of Love

I thought this story was very interesting, but it certainly didn't turn out the way I expected it to. What I found so surprising was the way she agreed to go ahead and sleep with Master Chozaemon in the end of the story just because she was accused. After the lady of the house accused her of sleeping with him, Osen said, "My sleeve is already wet with tears. Having suffered the shame, there is nothing left to lose. I shall make love to Chozaemon and teach that woman a lesson" (Saikaku 602). After she said this, she and Master Chozaemon made a promise to make love to each other. I also find it humorous how they went about doing this. I cannot seem to understand why they went to her bed, where her husband was sleeping soundly. I know that during this time period you could be put to death if you cheated on your husband, but the reason I thought this was so surprising is because of these two lines in the beginning of the story: "Once when a lighthearted fellow pulled her dress she responded with a full-throated shriek, leaving the man to bewail this unfortunate turn of events. After that no man would ever speak flirtingly to her" (Saikaku 591). These lines make it sound as though she would never fool around with any men, and yet she cheated on her husband to be with Master Chozaemon.
