My Fiancée's Best Friend Wore a Groom's Suit, So I Swapped…

Imagine standing at the altar in a tailored navy suit, waiting for the woman you love—and watching her walk toward you on the arm of another man. Not her father. Not a brother. Her best friend Julian, grinning in his own groom's suit like he's the one getting married.

That's the moment Ethan's wedding stops being a wedding and becomes a public execution.

Two Grooms and a Joke That Broke Everything

Ethan grips his cufflinks so hard the metal bites into his palm. Guests whisper. Cameras flash. Serena's excuse floats over the crowd: Julian just wanted to know what it felt like to wear a groom's suit. For fun.

On their wedding day.

Something in Ethan snaps—but not into tears. Into something colder and bolder. He walks to the front, turns to the room, and throws the doors wide open:

"Looks like we've got a spare groom, so I'm opening the floor. Anyone want to be my bride?"

Serena's side laughs it off. Come on, Ethan, it's just a joke. Who else would marry you? The whole room waits for him to back down.

Then a chair scrapes.

A woman in an ivory dress rises slowly from the guest section. Brown hair loosely pinned, a few strands falling by her ears. She slides a plain band off her pinky, turns it between her fingers, and walks calmly onto the platform. She slips her arm through Ethan's and rests her head on his shoulder.

"My name is Vivian Laurent, and I'll marry you."

Gasps. Flashbulbs. And a groom who can barely breathe, nodding yes.

The Kiss That Ended a Three-Year Lie

Serena loses it. She shoves her way forward, screaming that this is her fiancé, that Ethan is embarrassing himself, that he'll come crawling back. Julian smirks behind her—until Ethan tells him to stay out of it, and that smirk drops.

Then comes the part that guts her. The officiant asks for the kiss. Ethan hesitates, fists clenched—and Serena, certain he doesn't have the guts, keeps taunting him. So he kisses Vivian. Properly. In front of everyone they know.

Serena pushes Vivian. Ethan steps between them, and when Serena wails about him kissing another woman in front of her, he fires back the line that lands like a slap:

"Why is it different when it's me? You had no problem kissing him."

He and Vivian walk out hand in hand. Behind them: Serena screaming, her mother shrieking, the crowd devouring every second.

At city hall, Ethan's phone won't stop buzzing. Serena. Her parents. Julian. He declines, then blocks every single number, one after another, and lets out a long breath. Less than forty minutes later, a gold-sealed marriage license sits in his hands. Their photos side by side—her ivory dress now grass-stained, his suit wrinkled—and at a glance, they almost look like a real couple.

Then Vivian offers him a key. Her place. Separate rooms.

Three Rules, One Very Blurry Line

Back at his old apartment for clothes, Ethan finds Serena waiting in the lobby, eyes bloodshot, the handprint still visible on her cheek. She wants him to come back, apologize, move on. She still thinks she's the prize.

"You make me sick, Serena. Everything that's happened between you and Julian, and he's still just a best friend. You're not worth marrying."

At Vivian's flat, the deal gets laid out plainly. Rule one: no interfering in each other's lives. Rule two: six months, then a clean divorce. Rule three: separate rooms, doors locked at night, no crossing over. Ethan agrees to all three.

Serena, of course, doesn't agree to any of it. She shows up at Vivian's building, and Vivian doesn't flinch:

"This is my legal husband. You're ancient history."

Then security gets called, and Serena is escorted out.

What Ethan doesn't expect is the quiet. Vivian keeps every rule—and still finds ways to look out for him. She brings him pale green flowers edged in white instead of the red roses that used to trigger his allergies while Serena called him dramatic. She picks him up in a downpour with a towel for his head, soaking her own shoulder, and when he protests about their agreement, she smiles:

"The agreement doesn't say I cannot pick up my husband from work."

Then came the fever. Ethan burns up at 38.7, shivering under the blanket, and Vivian stays awake all night—cooling patches, warm towels, a spoon of medicine at his lip, her hand holding his until dawn. He wakes to find every blanket on him and her curled asleep in a chair, wearing only a thin sweater. From that night on, the contract's clean lines start to blur. She brings home desserts he mentioned once. He brews her coffee. Neither of them mentions the deadline.

Serena's Last Cards—and What Comes Next

But peace never lasts. Serena starts calling every mutual friend, painting herself as the victim—the heartless fiancé who ran off with a stranger. She shows up at their door past eight at night, gift bag in hand, sobbing that she's done with Julian, begging for five minutes. Neighbors peek into the hallway. Vivian doesn't hesitate—she calls security.

Serena's world keeps collapsing. Julian blames her for the fallout at a bar. Friends drift away. Drunk, she calls Ethan; he hangs up and blocks her. She kneels outside their building, and security removes her. The moment that truly breaks her is seeing the marriage certificate with her own eyes.

And Ethan? He's standing firmer than ever, watching Vivian handle every intrusion with that calm smile—while neither of them dares to say what everyone can see coming.

Six months. Three rules. Two people who were never supposed to fall for each other. One question hanging over all of it: who breaks the contract first?
