Miki Haruse, an employee in the sales department, harbors a competitive streak towards Hitoshi - her colleague who consistently achieves top grades. After breaking a record of consecutive sales losses and triumphantly claiming victory, Miki challenged Jin to a penalty game of giving her a massage. However, Jin appeared unenthused and chided Miki with the saying, "never regret." Despite this setback, Jin persistently arranged for a massage during his hotel visits, all the while teasing Miki about their previous game, daring her to "feel it" and lose. As their physical interactions escalated, Miki reached new heights of pleasure, becoming enthralled in the romantic rivalry between herself - an office lady with a penchant for dishonesty, and Hitoshi - the colleague who harbors hidden feelings.
