It was a bright Saturday afternoon in Manhattan, and Blair Waldorf was practically glowing with excitement.

“You have to say yes,” she insisted, hands clasped together, eyes sparkling like diamonds. “I can’t imagine my wedding without you. Maid of honor, Y/N. It’s perfect, right?”

You froze for a split second. Perfect? The word felt heavier than ever.

“Yes… of course,” you said, smiling. Inside, your stomach twisted. Because Nate—the Nate she had dated for years—was your secret.

The following weeks were a nightmare of glitter, bridesmaid fittings, and endless phone calls with Blair about floral arrangements, seating charts, and the perfect shade of blush.

Serena noticed first.

“You’re stressed,” she said, leaning against the doorway of your apartment. “And you keep checking your phone every five seconds.”

You laughed nervously. “It’s just Blair. Wedding planning, you know?”

Serena raised an eyebrow. “Or… Nate?”

You choked on your coffee. “What? No! I mean… yes… but we’re careful. He knows to keep it quiet.”

Serena smirked. “Manhattan’s secrets never stay buried for long.”

At Blair’s first bridal fitting, you were there, helping adjust the train, offering advice, and pretending everything was normal. Blair was radiant, completely oblivious to the storm brewing behind her back.

Nate appeared just as she turned to admire herself in the mirror. “Looking beautiful, B,” he said, with a hint of habit in his tone.

You felt your stomach drop. Nate’s hand brushed yours as he handed you a swatch of fabric. Just a brush. But it set your heart racing.

Blair’s eyes sparkled. “See? I told you I needed you here. You and Y/N make the perfect team.”

One night, after a long day of dress fittings and floral tastings, Serena pulled you aside.

“You know this can’t last,” she said softly. “Blair is too sharp. She’ll find out eventually.”

You bit your lip. “I know. But I… I can’t give Nate up. Not now.”

Serena shook her head, amused and worried at the same time. “You’re playing with fire, Y/N. Blair’s kingdom, her wedding, her life… you’re dancing on the edge.”
