My Ex’s Sister Asked Me to Be Her Fake Fiancé at a Family Wedding, but One Hotel Bed Turned the Lie Into Something Neither of Us Could Take Back

The drive down Highway 1 was supposed to be a masterclass in psychological preparation. We had two hundred miles of winding coastal road to establish our backstories, practice our fake hand-holding, and cement the illusion that we were a deeply in-love, modern couple heading toward marital bliss.

Instead, we spent the first hour arguing over Spotify playlists.

"If you skip Fleetwood Mac one more time, I am pulling over and making you walk to Monterey," I warned, glancing sideways at Brooke, who was furiously tapping away at her phone while shotgun.

"Fleetwood Mac is depressing divorce music, Leo. We are supposed to be *newly engaged*. We need upbeat indie pop to reflect our bright, shiny future," she shot back, though she didn't override my choice. Instead, she turned down the volume just enough for the sound of the Pacific waves crashing against the rocky cliffs below us to fill the cab of my truck.

The afternoon sun was dipping toward the horizon, casting a golden, cinematic glow over the asphalt. Outside the window, the jagged cliffs of the Big Sur coastline dropped steeply into the churning blue ocean. It was the kind of scenery that made you forget your own name—or, in my case, made you deeply aware of how close you were sitting to a woman you had sworn never to cross the line with.

Brooke shifted in her seat, tucking her legs underneath her. "You’re awfully quiet. Regretting the Japanese chisels yet?"

"I’m calculating the odds of us surviving your mother without committing a felony," I said, keeping my eyes on the road. "Tell me again why we couldn't just tell her the truth? That you were joking? That you're single and thriving?"

"Because *thriving* implies I'm not weeping into a pint of ice cream every time someone mentions weddings, which is what my mother assumes I do," Brooke sighed, resting her elbow on the center console. Her hand brushed against my forearm, sending a sudden, sharp jolt of static electricity straight up my arm. I gripped the steering wheel a little tighter. "You don't know what it’s like in that family, Leo. Every single gathering is an unspoken competition. Vanessa got the corporate lawyer and the penthouse. Natalie is getting the corporate architect and a destination wedding in Napa—well, Monterey."

"And what did you get?"

"Me?" A bitter, self-deprecating smile touched her lips. "I got the freelance graphic designer whose ex-fiancé traded her in for a twenty-four-year-old marketing assistant who unironically uses the word *synergy*."

"Hey," I said, my voice dropping instinctively. I took my eyes off the road for a fraction of a second to look at her. "Your career is real. You make your own hours, you do good work, and you don't ruin dinner parties by talking about stock portfolios. Derek didn't leave because you weren't enough. He left because he was a shallow, insecure coward who couldn't handle dating a woman with a backbone."

Brooke stared at me, her breath hitching slightly. The playful, defensive armor she usually wore around her shoulders seemed to crack, leaving behind something raw and exposed in the dimming light of the truck cab.

"You always say things like that," she whispered, her voice barely audible over the hum of the tires.

"What things?"

"Like you actually mean them." She swallowed hard, turning her face toward the window to watch the waves blur past. "Drive faster, Leo. If we don't make it to the Harbor Crest before dark, my mother is going to send a search party."

We pulled into the grand, stone-columned driveway of the Harbor Crest Hotel just as the last streaks of purple and orange faded from the sky. The hotel was an architectural masterpiece of old-money California elegance—tall glass windows, manicured hedges, and valets in crisp white shirts sprinting across the gravel.

My old, dented pickup truck looked like a stray dog that had wandered into a kennel of purebred show-dogs.

"Breathe," Brooke murmured as I put the truck in park. "Act like you own a yacht."

"I own a table saw and a set of chisels," I muttered, killing the engine. "This is as good as it gets."

We stepped out into the cool coastal breeze. Before I could even round the hood to grab our bags from the bed, the glass doors of the grand lobby swung open, and a whirlwind of perfectly coiffed silver hair and expensive perfume descended upon us.

"Brooke-ie!"

Eleanor Keller moved with terrifying speed for a woman who looked like she spent four hours a day at a country club spa. She bypassed her daughter entirely and latched onto me, planting a perfumed kiss on my cheek before I could register what was happening.

"And Leo! Oh, my goodness, the legend is finally in the flesh," Eleanor beamed, stepping back to inspect me from head to toe. Her eyes flicked over my flannel shirt and worn jeans with a micro-expression of practiced maternal dismay, but she covered it up with a glittering smile. "Brooke has been so secretive about you. But a woodworker! How wonderfully... earthy. Like something out of a magazine."

"Thank you, Mrs. Keller," I said smoothly, sliding a hand around Brooke’s waist on pure instinct.

The moment my palm settled against the soft fabric of her jacket, Brooke stiffened for a microsecond before leaning effortlessly into my side. Her shoulder pressed against my chest, warm and solid.

"Mom," Brooke said, her voice dripping with a practiced, sweet innocence that belonged in a Hollywood film. "Be nice to him. He drove two hundred miles just to watch you critique my posture."

"I never critique your posture, darling," Eleanor purred, linking her arm through mine as she turned us toward the grand entrance. "I simply suggest improvements. Now, come along! The rest of the family is already in the lounge, and Derek and Ashley just arrived from San Francisco. We have a lot of catching up to do."

I glanced down at Brooke. In the amber glow of the lobby lights, she was looking back at me with a mixture of panic and dark, wicked amusement.
