Chapter 3

“But he’s not exactly considerate. When he misbehaves, you have to help me teach him a lesson, alright? Tell him to be gentle like my brother-in-law instead of tearing up my things. It’s freezing!”

As she spoke, her eyes drifted playfully to her bare legs, the bruises on her knees glaringly provocative.

Her bold provocation struck me like a blow, but I steeled myself, swallowing the lump in my throat and refusing to let the tears spill.

Nolan’s glare darkened as he turned to Dione, his gaze sharp with warning. She quickly adjusted her expression, but her eyes flickered to the ring on my finger, and a sly laugh escaped her lips.

“Sister, is that a New Year’s gift from brother-in-law?”

“I guess we really are sisters; we have the same taste in men.”

“Look at this. My boyfriend gave it to me. Doesn’t it look like a set with your ring?”

“He said he wants to keep me tied to him forever. So childish, don’t you think?”

Before I could utter a word, Nolan’s voice sliced through the air, cold and sharp. “Can’t you see yours is a fake? Parading it around like that, don’t you feel ridiculous?”

Dione didn’t flinch. Her lips curled into a serene smile as she leaned forward, pulling a neatly wrapped box onto the table. “Sister, I brought some pears. Let’s split them later. I’ll go take a shower. You two enjoy.”

Her every word dripped with calculated innocence, but her gestures were a melody of provocation.

As the clock struck midnight, the building opposite us came alive, its windows blinking until they spelled out glowing words: "I LOVE YOU."

Nolan dropped to one knee, his gaze filled with reverence. “Baby, these ten thousand lights shine just for you. They’re a symbol of my love. Let’s get married after the New Year, okay?”

My phone buzzed, interrupting his declaration. It was a message from Dione.

"Sister, brother-in-law said the ruby reminded him of the color I bloomed under him for the first time. Are you still sure you want to marry him?"

I glanced at my reflection in the window, catching a glimpse of her twisted smile as she ground her teeth. The words on the screen burned in my mind, igniting a spark within me. I knew then that my time for revenge had finally come.

I smiled gently and nodded. “Alright.”

Nolan’s joy was uncontainable. He lifted me effortlessly and spun me around; his laughter filled with boyish delight. Tears glistened in his eyes, and his voice trembled with emotion. “You’ve given me the most unforgettable New Year’s Eve of my life.”

I let out a soft chuckle, brushing a stray strand of hair behind my ear. “The feeling’s mutual.”

His enthusiasm spilled over as he began calling a few friends, eager to celebrate and share the news of our engagement.

Turning to Dione, I smiled faintly. “Why not invite your boyfriend too? The more, the merrier.”

Her eyes darted instinctively toward Nolan, her expression unreadable. His face remained stoic, though a fleeting unease flickered in his gaze. “Do as your sister says,” he muttered, his tone devoid of warmth.

Hours later, Isaiah Crassus arrived, his tie slightly askew, his disheveled appearance hinting at the rush to get here.

What happened next silenced the room. With an air of nonchalance, Dione walked straight to him, her movements deliberate. She perched herself boldly on his lap, her arms sliding around his neck, leaving no doubt about her intentions.

She teasingly placed a cherry against his lips, her gaze, however, drifting back to Nolan, lingering just a moment too long.

Isaiah sat stiffly, the discomfort evident in his posture. His eyes darted nervously toward Nolan, betraying his unease.

I smiled knowingly, tilting my head ever so slightly. “Well, Nolan, it seems your secretary has managed to steal my sister’s heart.”

Nolan swirled his wine with deliberate calm, his expression cold and detached, though the faintest spark of anger flickered in his eyes. It was the same smoldering fury I remembered from the days when we had dated in secret, especially when his senior had insisted on asking for my number.

The moment Isaiah’s lips brushed against the cherry, Nolan moved without warning. He pulled me into his arms and kissed me fiercely, a gesture that was equal parts defiance and possession.

I fought back my rising anger, gently pushing him away, my movements controlled despite the heat in my chest.

Someone broke the tension with a laugh. “Not quite the same. She’s sharing cherries, and you’re sharing saliva!”

Nolan took my hand, his smirk playful yet edged with dominance. “What can I say? My baby’s sweeter than any cherry.”

The sound of glass shattering filled the room, cutting through the laughter. Dione’s wine glass lay in pieces, red wine blooming across her dress as she froze under the weight of everyone’s gaze.

Chapter 4

She froze in place, her teeth gently grazing her lip as her eyes shimmered with unshed tears, like a wounded fawn caught in headlights.

“Isaiah, can you come upstairs with me to change?”

Isaiah’s gaze flickered briefly toward Nolan, seeking some unspoken approval, before he followed her without a word.

Nolan, on the other hand, didn’t so much as glance their way. He lounged with his friends, the perfect host, his demeanor unbothered, as though nothing out of the ordinary had happened.

It wasn’t until he stepped away to take a phone call that he finally approached me. His voice dropped to a low murmur as he leaned close, his breath brushing against my ear. “Baby, there’s an issue with a contract. I need to take care of it.”

“Could you handle the guests for me?”

I nodded with a small smile, but the moment he turned away, I excused myself, murmuring something about fetching charcoal. Taking another route, I slipped upstairs unnoticed.

What I found stopped me cold. Nolan, his face dark and barely contained fury, carried Dione into the master bathroom, his movements jerky with frustration. In his anger, he didn’t even bother to close the door.

I steadied my breath, pulling out my phone. With a flick of my thumb, I hit record.

Nolan’s grip tightened as he set Dione in the bathtub, his bloodshot eyes seething with fury. Without a word, he turned on the showerhead, cold water splashing down on her.

“It was all just a show. Where do you get the nerve to flirt with him?”

Dione shivered, her teeth chattering. “Brother-in-law, it’s freezing.”

Nolan’s lips curled into a sneer, his voice dripping with disdain. “Now you’re cold? Watching you throw yourself at another man, I thought you were immune to the heat.”

Dione rose slowly, her fingers grazing the silk strap of her dress, her gaze lowering in a way that left little to the imagination.

“Without this, how would they know how much you care about me, brother-in-law?” she purred.

Nolan’s grip shot out, seizing her chin as his fingers traced her lips. “Did he touch you?”

Dione shook her head, her voice soft but certain. “Every inch of me belongs to you.”

The steam in the bathroom thickened as Dione handed the showerhead to Nolan, her voice a silken whisper, teasing and soft. “Brother-in-law, the water is so hot. Won’t you help me?”

Before she could finish, Nolan’s lips crashed against hers, his other hand tearing away the fragile silk that separated them.

Dione gasped, her voice trembling. "This belongs to my sister—"

"Shut up," Nolan growled, cutting her off with a harsh command, silencing her completely.

I watched the scene unfold before me, my heart numb, my emotions a tangled mess. When it was finally over, I quietly slipped my phone away and moved to the guest bathroom. There, I bent over the sink, my body heaving as I retched violently.

Later, Dione came downstairs with Isaiah, her expression radiant, almost glowing.

Someone couldn’t help but tease, "Secretary Crassus, what did you give Miss Cromwell? She went upstairs to change and came back looking so... different."

Isaiah’s face turned beet red, and he remained silent, eyes glued to the floor.

Dione shyly lowered her head but threw me a challenging glance; her voice laced with defiance. "My boyfriend, of course, showers me with love. Laugh all you want, but I’m happy."

Nolan, now in casual clothes, noticed the pallor on my face as he descended the stairs. His hand instinctively reached for my forehead.

"Baby, are you feeling unwell again?"

I nodded slightly. "Maybe I saw something disgusting... and it made me nauseous."

Panic flickered across Nolan’s face. "What disgusting thing?"

Following my gaze, he saw the grilling offal on the table, and his expression softened, his tension easing.

He quickly put out the charcoal fire, his voice sharp. "Who told you to grill offal? Stop it! Don’t make Isabella nauseous!"

I reached out to stop him, not wanting to be rude to our guests, especially on New Year's.

Nolan flashed me a smile, tapping my nose gently. "It’s fine. My wife comes first."

His friends joined in with teasing smiles. "Isabella, we all know you’re Nolan’s world."

"Remember when Troy slipped you a drink that made you sick? Nolan almost killed him."

"So don’t make us stay. If anything happens to you, Nolan will skin us alive."

A cold gust of wind swept through, stealing the smile from my lips.

If I hadn’t seen his betrayal with my own eyes, his sincere gaze would’ve made me believe I truly was his everything.

Chapter 5

After the New Year, Nolan began preparing meticulously for our wedding.

From the invitations to the favors, the venue to the banquet arrangements, he took charge of every detail, and his dedication was evident in every decision.

But the most touching gesture was the wedding gown he personally crafted for me. It was a pristine white dress with a subtle hint of red; his way of saying his heart belonged entirely to me.

That day, I feigned a bout of discomfort and retired to bed early, hoping to escape the tension.

Dione brought me a glass of milk, which I swiftly poured down the toilet.

In the dead of night, a sound stirred me awake.

Dione was lying between me and Nolan!

"Brother-in-law, how about you join me for a class reunion?" she purred.

Nolan’s voice was low, filled with warning. "Are you out of your mind? If your sister finds out, I swear I’ll kill you."

Dione pointed at the empty glass on the bedside table.

"My sister’s been struggling to sleep. I slipped some sleeping pills into her milk. She won’t wake until morning."

"With her right next to us, don’t you think it’s... thrilling?"

In an instant, Nolan’s demeanor shifted. He smiled darkly and reversed the situation. "Let’s see how well you handle this."

Dione leaned in, and the bed shifted beneath their movements, sending my heart tumbling into a bottomless abyss.

I turned away, clutching the blanket so tightly my knuckles turned white, desperate to steady my shaking hands.

I lost track of time as their “progress” finally came to a halt.

"How many more surprises do you have for me?"

Dione pouted playfully at Nolan. "Tomorrow’s class reunion has a theme. It’s going to be even more thrilling!"

The next morning, Nolan told me he had to go on a business trip to Willowcrest City for the day.

This time, he’d brought Isaiah along.

And, of course, Isaiah insisted on bringing Dione.

Nolan gave me an explanation with a chuckle. "Young lovers, right? Don’t worry, I’ll keep an eye on Dione."

I adjusted his tie and smiled, my voice steady. "Alright, thank you for your hard work."

"To show my appreciation, I’ve got a big surprise lined up for our wedding day."

He embraced me gently, his warmth sinking into my bones.

"Baby, I can’t wait for our wedding day."

Inside, I scoffed. Neither could I.

That day, Dione’s messages poured in like a tidal wave, relentless and overwhelming.

"Sis, so this is what clouds really look like from an airplane."

"Sis, my ex keeps asking for my number. My Brother-in-law helped me teach him a lesson. What do you think Brother-in-law would like as a thank-you gift?"

….

I printed out hundreds of pages of our chat history and transferred all the audio and video recordings from my phone onto a USB drive. I handed it all over to the wedding planner.

On the day of the wedding, the venue buzzed with excitement, filled with distinguished guests.

When the priest turned to me, asking, "Do you take Nolan as your husband?"

Amid the well-wishes and the eager anticipation in Nolan’s eyes, I smiled and said, "I do not."
