Three days before the wedding, my sister Mary’s laptop broke.

Desperate to finish editing a slideshow of childhood photos for my wedding, she borrowed my computer. That night, after she’d left, I went to close her QQ chat window when a message popped up.

It was from someone named “Adam”:

“Mary, still awake? You looked so beautiful trying on the wedding dress today. I couldn’t take my eyes off you.”

My fiancé’s name is Adam.

Rationally, I knew a man engaged to one sister wouldn’t send ambiguous messages to the other late at night. Yet my hands trembled as I opened their chat history.

Empty. Wiped clean, obviously, after every conversation.

Compelled, I didn’t close Mary’s QQ. Instead, I clicked into her space.

There was a group labeled “Visible to One Person Only.”

Shaking, I clicked in. That one person was Adam’s alternate account.

The latest post was from three hours ago—a photo of Mary in her bridesmaid dress.

The caption read: “They say I look better in this than the bride. Adam, what do you think? I really wish, one day, I could wear a real wedding dress for you.”

Below, Adam’s only comment: “In my heart, you look more beautiful than her in anything. Just wait a little longer, Mary.”

Scrolling further back, post after post, dense and endless, spanning six whole years.

Adam and I had been together for exactly six years.

And they had been entangled for six years.

Through it all.

I was drowning, forcing myself to read on, each word a fresh dose of poison.

The first post was from six years ago, in autumn, just one month after Adam and I had officially become a couple.

“Today, my sister brought her boyfriend home. That guy named Adam—when he smiles, his eyes sparkle like stars. What do I do… I think I’m falling for him too.”

The second post, after I brought Adam to a family gathering.

“He peeled a shrimp for me. My sister saw and joked that he was playing favorites. He laughed and said, ‘Mary’s the little sister, it’s only right.’ But I caught the flicker of tenderness in his eyes. That wasn’t a look for a sister. I know… I’m different to him too.”

A wave of nausea hit me.

I remembered that gathering. I’d even teased Adam for being so focused on peeling shrimp for Mary. He’d patted my head and said, “Babe, Mary’s your favorite little sister. If I’m not good to her, you’d be upset.”

Back then, I was utterly moved. I’d thought he loved everything connected to me—that he was a good man I could rely on.

Turns out, it wasn’t love for all that was mine. It was an impulse he couldn’t control.

Further down, the evidence showed their relationship progressing rapidly.

During our second year of university, I was swamped preparing materials for a graduate school recommendation. Adam said he’d come to the library with me, but he was never there. When I asked, he claimed the boys’ dorm was too noisy, so he’d found a quiet study room.

But in Mary’s space, she’d written: “Meeting Adam every day at our usual spot on the third-floor corner, then studying together, is my happiest time. He brings me warm milk, helps me with calculus. Watching his serious profile, I wish time would just stop here. Sister, I’m sorry. I really can’t control myself.”

Can’t control herself?

I couldn’t hold back a cold, bitter laugh.

I remembered how she’d come to me back then, all earnest concern, asking, “Sis, Adam is really such a great guy. You better keep a close eye on him. Don’t let some other woman steal him away.”

Looking back now, *she* was the one wearing the family mask—the deepest-hidden “other woman.”

But what shattered me completely was the incident where I gave up my spot in the master’s program.

I’d already been accepted into our university’s master’s program. But Adam was desperate to start his business. He pulled me into an all-night talk, hoping I’d join him in the struggle, be his most solid support.

"Once my company goes public, Sophie," he said, "I'll give you the grandest wedding the world has ever seen."

Swept away by his ambition and his sweet promises, I went to the department office the very next day and signed the waiver, relinquishing my guaranteed graduate spot.

My advisor, Professor Nicholas, was furious—practically ready to disown me. I was gambling with my future, he said.

But back then, my whole world revolved around Adam. To me, sacrificing for love was the noblest thing in the world.

Mary’s social media, however, told a different story.

"Adam says he’s almost convinced my sister to give up her spot," she posted. "I feel a little bad for her, but for our love, someone has to make a sacrifice, right?"

So my earth-shattering sacrifice was merely a stepping stone for their sordid affair.

An icy chill shot through me, absolute and deep.

Her feed overflowed with photos of them together.

While I was visiting my parents, they were catching a midnight movie. During my training trip, they strolled through an amusement park like any happy couple. And while I pulled all-nighters for company projects, they were embracing in the wedding home I’d decorated with my own hands.

One photo stood out. The backdrop was our wedding home’s bedroom—the very bed I had chosen with such care.

Mary wore Adam’s white dress shirt, her hair slightly damp, leaning lazily against his chest with a smile like the cat that got the cream.

The caption read: "Getting a little preview of being the lady of the house. Feels good."

The date? The night I was away at an industry conference in the neighboring city.

I couldn’t take it anymore. I rushed to the bathroom, sank to my knees, and retched beside the toilet until my vision blurred—as if I could purge not just six years of love and trust, but my very guts along with them.

In the mirror, my face was ghostly pale, eyes bloodshot. A lost soul. A wandering ghost trapped in the world of the living.

It was almost laughable—the wall still held our wedding portrait. There I was, smiling brilliantly, leaning against his side, my eyes brimming with nothing but happiness and hope.

Now, looking at that photo, I could only see the biggest joke of my life.

I didn’t sleep a wink that night.

When dawn broke, painting the sky a pale gray, I watched the light seep in—and made a decision.

I couldn't just let this go.

Six years of my youth. Six years of giving everything I had. In return, the two people I trusted most had betrayed me. If I went to them now, weeping and demanding answers, all I’d get were hollow apologies and crocodile tears.

That would let them off far too easily.

I wanted them to stand on the very stage I'd once dreamed of, the one I'd built for my own happiness, and tear off their masks of hypocrisy with their own hands. I wanted them to face judgment from everyone who mattered.

Calmly, I got up, washed my face, and applied my makeup, carefully covering the exhaustion etched into my skin.

At breakfast, Mom noticed my pallor. "Sophie, sweetheart, is it just pre-wedding nerves? Don’t push yourself too hard. Let me and Mary handle the details."

Beside me, Mary chimed in immediately, eagerly placing a steamed bun on my plate. "Exactly! Sis, don’t worry about a thing—I’ve got the wedding covered! You just focus on being the most beautiful bride."

She beamed with that familiar, innocent smile, perfectly playing the role of my sweet, devoted little sister.

Looking at her guileless face, a cold laugh echoed inside me. On the surface, though, I offered a gentle smile. "Alright then, I’ll leave it to you. Oh—how’s that video edit coming along? The one I asked you to trim yesterday?"

"Almost done! I’ll polish up the details today. Promise it’ll be perfect!"

"Mmm," I nodded, feigning casualness. "Mary, you still haven’t picked your bridesmaid dress, right? Yesterday I saw this wedding gown—strapless, absolutely ethereal. I think it would be perfect on you. Why don’t you just wear that? After all, my maid of honor should be the most stunning woman at the wedding, too."

Mary’s eyes lit up instantly, a flicker of surprised delight crossing her face. "Sis, I couldn’t possibly! A bridesmaid wearing a wedding dress?"

"Why not? Rules are made to be broken. You’re my only sister—I want you to. It’s settled. We’ll go to the bridal shop this afternoon." My tone left no room for argument.

A trace of barely-concealed glee—and triumph—flashed across Mary’s features.

She probably thought this was the ultimate reward for her "hard work."

All I wanted was to see her face when she stood there, draped in white silk on the spot that should have been mine, waiting for vows that would never come.

That afternoon, I took Mary to the most exclusive bridal boutique in town.

I personally selected an intricate, astronomically expensive gown for her. As I watched her twirl and preen before the mirror, listened to her sigh, "Sis, it’s so beautiful… I never want to take it off," my own heart remained a still, cold pond.

Adam showed up too. The moment he saw Mary in the wedding dress, the awe and longing in his eyes were impossible to miss.

He walked over and, with a naturalness that stung, adjusted the train of her gown. "So beautiful," he murmured.

He said it quietly, but in the hush of the boutique, I heard every syllable.

Mary lowered her head, a blush coloring her cheeks.

When Adam turned to me, his face had already smoothed into that usual, gentle smile. "Sophie, look. Doesn’t Mary look like a fairy princess in this?"

I smiled and nodded. "She does. Absolutely stunning. We’ll take this one."

Then I swiped my card for the full amount and told them, "This dress is my gift to you, Mary. On the wedding day, you’re going to take everyone’s breath away."
