My beloved wife, Hikaru, decided to re-enroll in university to obtain a qualification. Because she's so sociable, my heart is constantly filled with anxiety. In a photo taken at her seminar drinking party, she was happily chatting with some good-looking guy. But men like that—she'd surely hate them. It had to be that way... Right? Yet, day by day, her return home grew later, and her communication with me faded. Impossible. She's a married woman. She wouldn't get involved with some random man... I must've sensed it all along. But I didn't want to believe it. In the end, I discovered my wife was coming home late every night, defiled after repeatedly having sex with a worthless younger guy who never even attended lectures, getting creampie after creampie inside her.
