The cool glass of the medical bottle pressed against my palm as I settled onto the edge of the bathtub. My heart hammered against my ribs, a mixture of anticipation and fear coursing through me. This was it—the moment that would finally make me whole in Xander's eyes.

I uncapped the bottle, the soft pop echoing in the tiled bathroom. The liquid inside looked slightly different than I remembered from my previous appointments—clearer somehow, with a subtle sheen that caught the candlelight. But my nerves were too frayed to question it.

"Just breathe, Katherine," I whispered, my fingers trembling as I dipped them into the cool gel.

The first touch against my skin felt wrong—too viscous, too clingy. I paused, frowning slightly, but pushed the thought aside. Dr. Chen had warned me that each formulation might feel slightly different.

I applied a generous amount to my most sensitive areas, the way I'd been instructed countless times before. The coolness was supposed to be immediate, followed by a gentle numbing sensation that would allow my body to relax enough for Xander.

But the coolness never came.

Instead, heat bloomed across my skin—not the warm flush of arousal, but an intense, searing burn that made my breath catch in my throat. It felt like I'd poured acid onto my most delicate tissues.

"What's happening?" I gasped, jerking my hand away.

The sensation intensified, spreading outward in waves of agony. When I looked down, I saw that the liquid had begun to change consistency, thickening and turning cloudy where it touched the moisture of my skin.

"No, no, no," I whimpered, panic rising as I realized something was terribly wrong.

I grabbed a nearby washcloth, desperate to wipe away the substance before it could do more damage. But as soon as the fabric touched my skin, a fresh wave of pain tore through me—the friction was accelerating the reaction.

"Oh God!" I cried out, dropping the cloth as my thighs began to stick together.

The realization hit me with horrifying clarity: this wasn't the medical lubricant. This was something else entirely—something that was literally bonding with my skin.

I tried to stand, but my legs wouldn't cooperate. The sticky substance had spread, creating a chemical burn that felt like my skin was being torn apart from the inside. I collapsed onto the bathroom floor, my screams echoing off the marble tiles.

"Xander!" I shrieked, my voice breaking with desperation. "Xander, help me!"

Footsteps thundered down the hallway, and the bathroom door swung open with such force that it slammed against the wall.

"Katherine?" Xander stood in the doorway, his expression not of concern but of irritation. "What the hell is going on?"

I looked up at him through tears of agony, my body convulsing with pain. "Something's wrong," I choked out. "It burns—it's burning me!"

His eyes flicked over me, taking in my collapsed form on the floor, but there was no compassion in his gaze—only annoyance.

"You're doing this now?" he said, running a hand through his hair. "On my birthday?"

"I'm not doing anything!" I sobbed, reaching toward him. "Please, help me up!"

Xander took a step backward, his jaw tightening. "This is exactly what Brittany warned me about. You're being dramatic again."

"Dramatic?" I gasped, disbelief momentarily overriding my pain. "Xander, I need to get to a hospital!"

"Stop it," he snapped, his voice rising. "You're ruining the whole vibe of tonight. We were finally going to—"

"I know what we were going to do!" I screamed, interrupting him as another wave of agony ripped through me. "But something is seriously wrong!"

He looked at me for a long moment, then shook his head in disgust. "I can't deal with this right now."

As he turned to leave, his eyes caught something on the counter—the empty bottle. For a split second, I thought he might realize what had happened, might understand that I wasn't faking my suffering.

Instead, he picked it up and hurled it against the wall. The glass shattered, fragments raining down around me as he stormed out, slamming the door behind him.

"Xander!" I screamed after him, but he was already walking away, his footsteps fading down the hallway.

I lay there on the cold tile floor, my body burning as if I'd been set aflame from within. Through the haze of pain, I heard the distant sound of laughter—Brittany's distinctive giggle floating through the apartment.

And in that moment, as my vision began to blur and darkness crept in at the edges, I realized that this had been no accident.

The bathroom door creaked open again, and I looked up through tears of agony to see Brittany leaning against the doorframe. Her silhouette was backlit by the hallway light, creating a sinister halo around her figure. Gone was the fake sweetness she'd worn like a mask earlier. Now her face was a canvas of cold satisfaction.

"Need some help?" she asked, her voice dripping with false concern as she stepped into the bathroom.

I tried to speak, but another wave of pain tore through me, turning my words into a strangled cry. The substance had spread further, creating a chemical burn that felt like molten metal against my skin.

"Oh, Katherine," Brittany sighed, crouching down beside me. "Did you really think I wouldn't notice your little medical condition?"

She held up a small bottle—identical to the one Xander had smashed, but this one was full. The label read "Industrial Strength Super Glue" in bold red letters.

"You see," she continued, twirling the bottle between her manicured fingers, "I've been watching you for months. Poor little rich girl with her embarrassing problem." Her lips curled into a cruel smile. "Did you really think I wouldn't find out what you kept seeing Dr. Chen for?"

Horror washed over me as realization dawned. "You... you switched them," I gasped.

Brittany's laugh was like ice picks in my skull. "Took me three tries to get the perfect timing. Had to make sure Xander was distracted just long enough." She leaned closer, her breath hot against my ear. "Industrial grade, Katherine. The kind that bonds skin permanently."

My mind reeled with the implications. This wasn't just a cruel prank or jealous sabotage—this was attempted murder.

"Why?" I managed to choke out.

"Because you don't deserve him," she hissed, her pretty features twisting with hatred. "You don't deserve any of this." She gestured around at the luxury surrounding us. "Your money, your privilege, your perfect life. I've worked so hard to get close to Xander, and you waltz in with your trust fund and your... problems."

I needed help. The panic button—my father had insisted I carry it after a string of kidnappings in our social circle last year. It was in my purse, just ten feet away.

"Xander!" I screamed, summoning what little strength I had left. "Help me!"

Brittany's eyes widened momentarily before narrowing with calculation. She darted into the hallway, her voice rising in alarm.

"Xander! She's faking! She's trying to get you in trouble!"

I heard his heavy footsteps approaching, then his face appeared in the doorway, flushed with anger.

"What the hell is going on?" he demanded.

"I need my purse," I gasped, reaching toward where it lay by the sink. "The panic button—please, Xander."

Brittany appeared behind him, her hand on his shoulder. "She's trying to get you arrested, Xander. For what? Not sleeping with her? Think about your future."

Something dark crossed his face—fear, perhaps, or simply the weakness that had always lurked beneath his charm.

"You're pathetic," he spat, striding across the bathroom.

For a moment, hope flared in my chest—until I realized he was heading for my purse, not to help me but to prevent me from calling for help.

"No!" I cried out as he grabbed the small device.

With one vicious stomp of his foot, he crushed the panic button beneath his heel. The plastic casing splintered, electronics spilling onto the marble floor.

"There," he said, brushing his hands together. "Problem solved."

Brittany's triumphant smile made my blood run cold.

The glue was setting completely now, my skin fusing in the contorted position I'd collapsed in. The pain was unbearable, radiating outward from my core in waves that made black spots dance before my eyes.

"Oh God," I moaned, feeling bile rise in my throat.

I vomited onto the floor beside me, but couldn't move to wipe my mouth or clean myself. The humiliation burned almost as much as the chemical reaction still taking place on my skin.

"Look at you," Brittany whispered, kneeling beside me again. "The perfect Foster heiress, covered in vomit, glued to her own bathroom floor."

She reached over and picked up my phone from the counter, dangling it just out of reach.

"Your daddy's security team can't help you now," she said, her voice almost gentle as she slid the phone across the floor and into the far corner of the bathroom.

I watched helplessly as my last connection to the outside world skidded away, leaving me alone with my tormentors.

The room began to spin around me as shock set in. Through the haze of pain, I heard Brittany's voice as if from underwater.

"She'll die here, Xander. Infection, shock, whatever. And then I'll take her place. Her money, her connections..." She paused, her voice dropping to a whisper. "Her boyfriend."

Darkness crept in at the edges of my vision as I realized with horrifying clarity: this wasn't just an attack—it was an execution.

The pain radiating through my body had become a living entity, clawing at my insides with razor-sharp talons. I lay helpless on the bathroom floor, my skin fused in a grotesque position, watching through tears as Brittany paced before me like a predator savoring the moment before the kill.

"Xander," she called out, her voice honey-sweet but laced with venom. "You need to think about what happens next."

He appeared in the doorway, his face pale but not with concern for me—with fear for himself. The man I thought loved me was crumbling before my eyes, transforming into something unrecognizable.

"We can't call 911," Brittany said, placing a manicured hand on his chest. "Think about it. The Fosters will destroy you."

Xander's eyes darted between her and me, conflict evident only in the tightness of his jaw. "But she's—"

"She's faking," Brittany interrupted, her voice dropping to a conspiratorial whisper that somehow felt more menacing than a shout. "This is exactly what I warned you about. She's manipulating you, Xander. She's always manipulated you."

I tried to speak, to scream that I wasn't faking the agony that was consuming me, but my voice emerged as little more than a wet gurgle. The glue had spread further, sealing my thighs together and beginning to bond with the marble floor beneath me.

"If we call for help now," Brittany continued, her fingers tracing patterns on Xander's chest, "her father will know you were here. He'll know you 'hurt' his precious princess. Do you think Franklin Foster will let that slide? Your career, your future—gone."

Xander's shoulders slumped in defeat. I watched as whatever decency he might have possessed crumbled under Brittany's influence.

"What do we do?" he asked, his voice hollow.

Brittany's smile was triumphant as she glanced down at me. "We wait it out. Or let nature take its course."

The bathroom tiles were cold against my cheek as consciousness ebbed and flowed like a toxic tide. Through the haze of pain, I felt Brittany crouch beside me, her breath hot against my ear.

"Poor Katherine," she whispered, her voice intimate as if sharing a secret with a lover rather than tormenting a victim. "Did you really think someone like you deserved everything you have?"

I couldn't respond, couldn't even whimper as another wave of agony washed through me.

"I've been planning this for months," she continued, her words slithering into my brain like poison. "Every detail. Every contingency." Her fingers brushed against my hair in a mockery of tenderness. "You see, when you die here tonight—and you will die, Katherine—I'll step into the void you leave behind."

My heart stuttered in my chest as her meaning became clear.

"Your trust fund, your connections, your perfect life," she murmured. "And best of all, Xander. He'll finally see that I was the one who truly understood him all along."

Black spots danced at the edges of my vision as shock began to set in. The glue had created a chemical burn that was spreading through my system, and I could feel my body shutting down in response to the trauma.

"I'll wear your clothes, use your accounts," Brittany whispered, her voice becoming distant as my consciousness faded. "By the time anyone realizes what happened, I'll be long gone with everything that should have been mine."

---

Through the fog of pain and approaching unconsciousness, I heard the distinctive sound of a camera shutter clicking. Brittany stood over me, her phone held high, capturing my humiliation and agony from every angle.

"These will be useful," she said, reviewing the images with clinical detachment. "Either to stage this as some kind of... deviant accident when the time comes, or perhaps as insurance against your father's wrath."

She adjusted the lighting, directing Xander to hold my arm at a specific angle to better showcase the damage. "Perfect," she murmured, snapping more photos. "This is the money shot."

Xander had retreated to the living room, the sound of champagne cork popping echoing through the apartment. Music blared from the surround sound system—something upbeat and obscenely cheerful that contrasted horrifically with my suffering.

"Turn it up," Brittany called out to him. "We don't want anyone hearing her."

The volume increased, drowning out my whimpers and gasps. Through the bathroom door, I could see Xander's silhouette in the living room, champagne flute in hand, his movements mechanical as he drank to numb his guilt.

Brittany crouched beside me one last time, her smile radiant with triumph. "Don't worry, Katherine. By morning, you'll be nothing but a tragic headline—and I'll be stepping into your shoes."

As darkness crept in at the edges of my vision, I heard her footsteps fade away, leaving me alone with the searing pain and the growing certainty that no one would find me in time.
