What Do You Mean I'm an Incompetent Husband?

After being reborn in neon-lit Tokyo, Nangong You lived an uneventful life for seventeen years before the System finally showed up. And the first thing it did was throw him into an instance, where he became an impotent husband tasked with protecting his still-charming wife from people with designs on her. After finally clearing it, Nangong You returned to the real world and received the System's reward: the ability to read minds. He thought he could finally enjoy a peaceful life, but was horrified to discover that the world he'd lived in for over a decade wasn't quite normal. Why does his cold and aloof deskmate have a round-the-clock plan to stalk him in her mind? Why is his antisocial neighbor, whom he's never even met, fantasizing about him at home? Why are his little sister's thoughts so completely at odds with the cruel things she says to his face? And more importantly, why does the transfer student look so much like his wife from the game? What do you mean it wasn't a game, it was real life? What do you mean I'm that impotent husband???

P.S. This is a story about a pure-love warrior mercilessly crushing NTR.
