When my best friend Jessica asked me to watch her house while she went on a work trip, I didn’t hesitate. We had been inseparable since college, and even as life pulled us in different directions, our bond remained strong. But something always felt off about her husband, Mark—too polished, too smooth, with cold eyes that never quite matched his warm smile.

When she asked me to feed her cat and water the plants, I couldn’t help but ask why Mark couldn’t do it. “It’s not a man’s job,” she said, brushing it off. The tension between us grew, old doubts resurfaced, and I agreed to help—reluctantly. When I arrived at her house days later, something didn’t feel right. I fed the cat, checked the mail… and then I heard laughter upstairs. I froze. It was Mark. And another woman. What I saw and heard next would shatter everything I believed about loyalty—and what happened afterward shocked me even more.
