My sister threw champagne in my face and smashed red velvet cake into my wedding dress while 200 guests watched—but she had no idea I already knew about her secret with my fiancé.

The Grand Ballroom of the Grand Harbor Hotel was a cathedral of manufactured joy.

Chandeliers glittered overhead like frozen waterfalls; white hydrangeas cascaded from every table center prime; and the hum of two hundred guests clinking silverware against crystal glassware created a deafening, festive roar.

At the center of the head table sat the wedding cake—a magnificent, five-tier architectural marvel covered in smooth white fondant and delicate sugar pearls. Inside, hidden beneath the pristine white exterior, was rich, crimson-dyed red velvet cake. My absolute favorite.

The dinner service passed in a blur of polite small talk and forced smiles. Mark sat beside me, staring fixedly at his plate of roasted duck, barely touching his food. Across from us, Lily was already three glasses of champagne deep, laughing loudly at something Kyle—who had somehow snuck into the reception as her plus-one—whispered in her ear.

Then came the toasts.

My father stood up first, raising his crystal flute with a warm, sentimental smile. He spoke about how I had always been the rock of the family—the dependable one, the daughter who never caused trouble, the anchor in every storm.

My mother wept openly into her napkin, nodding proudly.

When Dad sat down, Lily abruptly stood up, swaying slightly on her Louboutins. She didn't wait for the MC to hand her the microphone; she simply reached across the table, snatched it from the stand, and tapped the grille until the speakers emitted a sharp, piercing whine.

"Testing. Testing. Okay, everyone shut up for a second," Lily announced, her voice echoing shrilly through the ballroom.

A heavy, uneasy hush fell over the room. Two hundred heads turned toward the head table.

Mom frowned, half-rising from her chair. "Lily, honey, maybe give the mic back..."

"Relax, Mom," Lily snapped, waving her hand dismissively. Her eyes locked onto mine, glassy, dilated, and burning with a toxic mixture of triumph and long-suppressed venom.

She turned the microphone toward herself, swaying slightly as she leaned against the floral arch behind her chair.

"To my sister Grace," Lily began, her voice dripping with a saccharine sarcasm that made the hair on my arms stand up. "The perfect bride. The perfect daughter. The corporate climber with the pristine little apartment and the perfect husband."

People laughed nervously, unsure whether this was a joke or a mental breakdown.

Lily didn't laugh. Her face twisted into something hard and ugly.

"You know, it must be exhausting being you, Gracie," she continued, stepping out from behind the table and walking unsteadily toward my chair. "Always doing the right thing. Always following the rules. Always making the rest of us look like absolute crap just by existing."

Mom stood up fully now, her face pale. "Lily! That is enough. Sit down right now."

Lily ignored her completely, her gaze fixed entirely on me like a predator locking onto a wounded fawn.

"You think you’re better than me, don’t you?" she hissed, her voice rising in pitch until it echoed off the crystal chandeliers. "Your perfect job. Your perfect life. Your perfect wedding."

My heart didn't even accelerate. I sat there with my hands folded in my lap, watching her with the detached curiosity of a scientist observing a specimen under a microscope.

I knew what she had done with my "perfect husband." I knew about the hotel rooms. I knew about the blue silk dress. I knew about the lies whispered in the dark while I was working late to pay off her art school tuition.

"You think you deserve all this," Lily sneered, stepping right up to the edge of the head table.

She reached out, grabbed a flute of champagne from a passing waiter's tray, and stared down at me with an expression of pure, unadulterated malice.
