My sister ran away, so I married her billionaire

The silk of my sister's wedding dress feels heavy on my skin, like a cold weight pressing down on my chest. I stand in front of the tall dressing room mirror, staring at my reflection, but I don't recognize the person looking back at me. This dress was made for Celeste. It fits her tall, perfect body like a glove, hugging her waist and flowing down to the floor in a cloud of white lace. To me, it feels like a costume. I pull at the tight collar, gasping for air as the panic inside me grows stronger.

"Elena, stop fidgeting," Mother says sharply, walking past me with her hands full of expensive pearl pins. She doesn't even look at me. Her eyes are fixed on the doorway, waiting for Celeste to return. "If you wrinkle that dress before the photos, your father will have a fit. Everything has to be flawless today."

I drop my hands to my sides and bite my lower lip. Flawless. That is the only word that matters in the Marlowe family. Celeste is the flawless one. She is the beautiful, confident older sister who always knows what to say, who inherited our mother's grace and our father's ambition. I am just Elena, the quiet younger sister who stayed away from the family business to hide behind sketch pads and interior design plans. For my whole life, I have lived in her shadow, always expecting less and asking for even less, knowing that whenever our family has to choose between us, Celeste will always be the one who matters more.

Except, today, Celeste isn't here.

A soft knock echoes on the heavy oak door, and my father steps into the room. His face is as pale as a ghost, and his hands are shaking so badly he hides them behind his back.

"Is she ready?" Mother asks, turning around with a bright, fake smile on her face. "The guests are already seated. The cameras are rolling."

"No," Father says, his voice tight and shaking. "She is not ready. She is gone."

Mother freezes. The pearl pins slip from her fingers and scatter across the marble floor with a sharp clatter. "What do you mean, gone? The ceremony starts in ten minutes! Where is Celeste?"

Father doesn't look at Mother. He looks straight at me, his eyes wide with a desperate, terrifying plea. He holds up a small, folded piece of pink hotel stationery. "She left a note. She said she couldn't marry him. She packed a small bag and drove away before sunrise. She told us not to look for her."

My breath catches in my throat. Celeste ran away. My sister, the golden girl who was supposed to marry the most powerful billionaire in the country, just packed up and left.

"We are ruined," Mother whispers, pressing her hands to her face. "The business... the merger with Vale Industries... If Adrian Vale finds out he has been humiliated in front of the entire financial world, he will destroy us. Your father's company will go bankrupt by tomorrow morning."

I stand there, frozen in the oversized wedding dress, watching my parents fall apart. I know who Adrian Vale is. I met him at a family dinner a few weeks ago, and just the sound of his voice made my heart race with a strange, impossible familiarity. He is thirty-two, ruthlessly cold, impossibly rich, and terrifyingly smart. He is a man who never loses. And if he finds out my sister ran away from the altar, he will make sure my family loses everything.

Father walks over to me slowly, his footsteps heavy. He stops right in front of me, reaching out to grab my cold hands.

"Elena," he breathes, his voice cracking with desperation. "You have to help us."

I pull my hands back, shaking my head. "No. Father, no. What are you talking about? You can't be serious."

"It's the only way," he begs, tears pooling in his eyes. "If we cancel the wedding now, the bank will seize our assets. Hundreds of innocent employees who have worked for this company for twenty years will lose their jobs, their homes, everything. Only a bride can save this agreement. You have to take her place."

"Marry him?" I cry out, my voice echoing off the walls. "Marry Adrian Vale? Father, he was supposed to be my brother-in-law! He doesn't want me, he wants Celeste! This is insane!"

"Please, Elena," Father whispers, his voice breaking completely. "You are my only hope."

I look from my crying mother to my broken father, and I know I have no choice. I cannot let hundreds of innocent people suffer just because my sister got cold feet. My hands shake as I pull the veil over my face, hiding my terrified eyes behind the sheer white mesh.

Minutes later, the heavy church doors open.

The organ music swells, filling the grand cathedral with a loud, triumphant sound. I step forward, walking slowly down the long white aisle. Hundreds of wealthy guests sit in the wooden pews, whispering behind their hands, but I don't look at them. My eyes are locked on the end of the aisle, where a tall man stands waiting in a dark, sharply tailored suit.

Adrian Vale.

As I get closer, my heart beats wildly against my ribs. I expect to see anger on his face. I expect him to look at me with confusion or fury when he realizes the bride walking toward him is the quiet sister, not the golden one. But as I lift my gaze to meet his, the breath completely leaves my lungs.

He isn't surprised.

His dark, sharp eyes lock onto mine through the white veil, and there is no shock in them at all. Instead, a strange, intense heat burns in his gaze, like a predator who has finally cornered the prize he has been hunting for a very long time. He watches me step up onto the altar with a calm, confident certainty that sends a shiver straight down my spine. It feels as though he knew I was coming all along.

My hands are trembling as he reaches out to take my fingers. His touch is warm, firm, and impossibly familiar, instantly dragging up a forgotten memory of a dark, beautiful night three years ago with a stranger whose face I never truly saw, but whose voice I could never escape.

I look up at him, my chest heaving, wondering what kind of trap I have just walked into.

When I reach him, Adrian quietly says, "You have no idea how long I've been waiting for you."
