Forty-year-old Takanashi is an ikeoji (handsome middle-aged man) and a first-class businessman who is also a section chief at the sales department of Itsuboshi Trading Company. Takanashi is popular with the ladies, but he's been smoothly rejecting any passes made on him, and that is because he has erectile dysfunction! One of Takanashi's subordinates is 26-year-old Hiwatari, a handsome and young employee who's known for his excellent yet merciless work ethics, and Hiwatari here is actually in love with Takanashi. One day, one thing led to another and they somehow ended up spending the night together?! Will the budding pure love between the ikeoji chief and the ice-cold man help reignite the light in Takanashi's tower again? (Source: Kodansha, translated)
