A second chance love story.. Yukiha, a well-respected leader in her company's Human Resources department, is newly divorced. The reason: her husband's lack of interest in sex. She accidentally reveals this detail of her divorce to Saiki, a genius engineer and problem child at the company. He takes a liking to her and makes her an offer: "I'll tell you how to avoid a sexless marriage if you give me a good evaluation." But Yukiha isn't one to be toyed with.
