PRED-870 The story of my wife's infidelity after she went back to university. (By Yukimura Izuki)

My beloved wife, Itsuki, has decided to re-enroll in university to obtain a qualification. She's still young and beautiful, so I can't help but feel anxious. In a photo from a seminar drinking party, she looks like she's having fun with a handsome guy. But I know better than anyone that she prefers sincere men to playboys. There's nothing to worry about...she's a married woman, so surely no one would try to make a move on her. But contrary to my hopes, my wife is coming home later and later each day. I don't like it...I don't want to believe it! My wife skipping lectures and getting fucked repeatedly by younger men...it's impossible.
