Every Thursday, my wife comes home late. I work overtime just for the heck of it. One day, he notices that his subordinate, Mr. Hashimoto, also works overtime only on Thursdays. ``Would you like to kiss me?'' I couldn't say anything in response to his sudden words. From then on, every Thursday became a day for overtime and tongue-tied work. The infidelity at the office can no longer be settled with just a kiss, and finally, the affair ends in office sex.
