My beloved wife Yukine reenrolled in college to earn a professional qualification. She is sexy and popular, so I could never shake my anxiety. Then a photo from a seminar party showed her happily drinking with a handsome younger adult student. I told myself Yukine had already had her fill of playing around and was probably just looking after him, but she started coming home later and taking longer to reply. Could that cocky guy have seduced her over drinks, tongue-kissed her while she was drunk, and persuaded her to skip lectures for days of sex and creampies before sending her home with a body used by another man? Just imagining it makes me shiver with rage and feel as if I am losing my mind—even though there is no way anything like that could really happen.
