After My Fiancé Betrayed Me with My Sister

I should have known something was wrong the moment she walked through our office doors. Jenesis Ross—twenty-five, impeccably dressed, with a smile that never quite reached her eyes. But I was too busy reviewing quarterly projections to pay attention to the new intern's arrival.

That was my first mistake.

It took exactly seven days for her to map our entire company's power structure. I noticed her taking notes during meetings, assumed she was documenting projects. Only later would I realize she was cataloging relationships, hierarchies, and most importantly—weaknesses.

Mine included.

"Alyssa, have you met with the new intern yet?" Hudson asked one evening as we reviewed marketing strategies in my office. "She's got some interesting ideas about our UX redesign."

I looked up from my laptop. "The one with the sleek bob cut? No, not formally. Rebecca mentioned she's been making quite an impression."

"She quoted my entire TechFuture keynote back to me yesterday," Hudson said, his eyes lighting up in that way they did when his ego was being stroked. "Even the part about disruptive innovation models."

I tucked a loose strand of hair behind my ear, a nervous habit I'd had since childhood. "That's... thorough of her."

"She thinks we're playing it too safe with the Morgan account," he continued, not noticing my discomfort. "Says your approach might be too conservative."

My fingers stilled over my keyboard. "She said that? About a strategy she's had no involvement in developing?"

Hudson shrugged. "Fresh eyes, Lyss. Sometimes an outsider perspective is valuable."

I bit back my initial response. Hudson and I had built this company from nothing over seven years. We'd shared ramen noodles in our first tiny office space, celebrated our first million-dollar contract with cheap champagne, held each other through the failures and triumphs. And now he was valuing the opinion of someone who'd been here less than two weeks over mine?

I should have spoken up then. Another mistake.

Instead, I watched over the next three weeks as Jenesis systematically positioned herself in Hudson's orbit. She volunteered for high-visibility projects, stayed conspicuously late when Hudson was working, and somehow always managed to sit next to him in meetings.

The worst part? She was good. Genuinely talented, with insights that even I had to admit were valuable. But there was calculation behind every move—the way she'd defer to Hudson while subtly undermining my recommendations, how she'd mirror his body language during presentations, the carefully timed compliments that fed directly into his insecurities about being overshadowed by his brother.

It came to a head during our dinner at home. I'd prepared Hudson's favorite—herb-crusted salmon with roasted vegetables—hoping to create a moment where we could really talk.

"I'm concerned about Jenesis," I said, setting down my wine glass. "Have you noticed how she's constantly positioning herself against my strategies?"

Hudson laughed, the sound echoing through our modern open-concept kitchen. "Are you jealous of an intern, Lyss?"

"This isn't about jealousy," I said, feeling heat rise to my cheeks. "It's about
