Fiancé Cheated with Sister Chapter 1

I glanced at my father's old watch as I slipped my key into the lock, smiling at the thought that he would have loved Ryan. Six o'clock—two hours earlier than expected. The funeral home had been unusually quiet today, allowing me to finish the Henderson family's arrangements ahead of schedule. Perfect timing to surprise Ryan and finalize those last engagement party details for tomorrow night.

The apartment was silent as I stepped inside, setting my purse on the entryway table. A stack of cream-colored envelopes caught my eye—our wedding invitations, delivered this morning. I picked one up, running my finger over the embossed lettering. *Grace Mitchell and Ryan Walsh request the honor of your presence...*

"Ryan?" I called out, my voice echoing through our home. No answer.

Humming softly, I made my way down the hallway, the invitation still in my hand. Maybe he was napping. He'd mentioned a stressful meeting with clients earlier today.

The bedroom door was slightly ajar. I pushed it open, the words "Hey, sleepyhead" dying on my lips as the scene before me registered.

Time stopped.

Ryan—my Ryan—was tangled in our sheets with Madison, her dark hair spilled across the pillows I'd chosen when we moved in together. My sister's leg was hooked around his waist, her lipstick smeared across his neck. Our bed. The bed where we'd planned our future, whispered dreams to each other in the dark.

The wedding invitation slipped from my fingers, floating to the floor like a surrendered flag.

"Grace!" Ryan scrambled upright, pulling the sheet over them both. Too late. "This isn't—you weren't supposed to be home yet."

Not *it isn't what it looks like*. But *you weren't supposed to be home*. As if the crime was my early arrival, not their betrayal.

Madison's eyes met mine, wide with fake surprise but lacking any real remorse. "Grace, I... we didn't mean for this to happen."

The air in the room felt electric, charged with the destruction of everything I thought was real. My throat constricted as I struggled to find words, to make sense of the nightmare unfolding before me.

"How long?" My voice sounded foreign to my own ears—too calm, too controlled for the hurricane raging inside me.

Ryan stood, hastily pulling on his discarded jeans. "Grace, baby, let's talk about this rationally."

"Rationally?" The word broke through my shock, igniting the first spark of anger. "You want me to be *rational* about finding my fiancé in bed with my sister?"

"It was just a mistake," Madison said, clutching the sheet to her chest, her voice dripping with practiced innocence. "A moment of weakness."

"A moment." I repeated, my finger unconsciously tracing the outline of my father's watch. "Is that what you call this, Ryan? A moment?"

He ran his hand through his disheveled hair—the same gesture I'd once found endearing. Now it made my stomach turn.

"Look, if you want someone to blame, maybe look at yourself," he said, his tone hardening. "Do you have any idea what it's like, telling people my fiancée spends her days with dead bodies? The looks I get? The jokes?"

The words hit like physical blows. All those times I'd sensed his discomfort when I talked about work, the way he'd change the subject or suggest I consider a "more normal" career—it hadn't been concern for me. It had been shame.

"So this is because of my job? My *morbid* profession drove you into my sister's arms?" I gestured toward Madison, who was now quietly gathering her clothes, watching our exchange with calculating eyes.

"You're overreacting," Ryan said, reaching for me. "We can work through this. The engagement party is tomorrow—what will people think?"

Something inside me snapped. In one fluid motion, I yanked the engagement ring from my finger and hurled it at his feet. It bounced off the hardwood floor with a pathetic ping.

"They'll think you're exactly what you are," I said, my voice steady despite the tears threatening to spill. "A coward who couldn't even be honest about what he wanted."

I turned to leave, but not before catching Madison's expression—not guilt, not even triumph, but something worse: pity. As if I were the one to be pitied in this scenario.

"Grace, wait—" Ryan called after me.

But I was already walking away, from the ring, from the invitations, from the life I thought we were building. Each step felt like walking on broken glass, but I didn't stop. I couldn't. Because the truth was brutally clear now: I had been sleeping next to a stranger all along.
