The story of a wife who re-enters university and is slept with. (PRED-836)

My beloved wife, Yukine, is re-entering university to qualify. Because she's a sexy and popular wife, I can't calm down. In the photos from the drinking party at the seminar, she seems to be chatting happily with a handsome man younger than her. But since Yukine seems tired of partying, it's probably just a casual fling… I think, but she's coming home later and later every day, and our communication has become sluggish. Could it be with that frivolous man? Being hit on at a party, a drunken, deep kiss, skipping class to indulge in sex, Yukine coming home with a defiled body… Just imagining it sends chills down my spine and drives me crazy with anger. This shouldn't happen, not even if it does.
