SSIS-650 "Aren't there plenty of other young guys around?" That younger guy who pursued me and that summer filled with adulterous sex. Hoshimiya Ikka.

One day, Ichika is invited to a drinking party by a male employee of the company. At the drinking party, the young men in the team sit next to Hoshimiya one after another and say lip service, "There are a lot of Hoshimiya-san's fans in the company." However, Hoshimiya understood that it would be disgraceful for a married woman to take her younger boy's social cues seriously. However, Yuki, who has long admired Hoshimiya, who is older than her, aggressively enters the gap between Hoshimiya's heart and her vagina without worrying that she is married.
