The apocalypse hit. I planned to dump Zayne. An Incubus makes total dead weight in the wasteland.
Then, a glowing chat stream flooded my vision.
[Infected swarm the outside. Vesper booting a fragile Incubus from the RV guarantees his death.]
[She remains completely clueless. An Incubus familiar levels up through physical intimacy. She just needs to feed Zayne, and he mutates into the wasteland's ultimate apex predator.]
[Zayne gets his first taste, and infinite supplies unlock. But nope, this side character throws her survival ticket straight in the trash.]
I slammed the RV door. I shoved Zayne onto the sofa. I leaned in, trapping him against the cushions. Heat burned my cheeks.
"Zayne you hungry?"
Chapter 1
My rations were scraping the bottom of the barrel. I stared at the pathetic stack of canned food left in the pantry. A dark thought crawled into my mind. I needed to kick Zayne to the curb.
For the past ten days, Zayne refused to eat. He was saving his share of the rations for me. But I saw the physical toll.
The RV had two cramped beds. Deep in the night, Id hear him curled up under his thin sheets, his breath catching in his throat. Muscles spasming as brutal hunger cramps twisted his gut. Zaynes true form was a serpent. And urban legend warned that a starving snake would eventually swallow its master whole. I wasn't about to become snake food just because he had a pretty face.
Back when I first graduated college, my parents had handed me the keys to a custom Airstream. They had wired a hundred grand to my account for a cross-country road trip. Concern for my safety on the road led me to an underground black-market auction. I needed protection. A familiar. My eyes were locked on a top-tier Phantom-Eye Direwolf. Raw, lethal muscle.
Then Seraphina swooped in. She flexed her trust fund, dropping two hundred grand to snatch the Direwolf right out from under me.
I refused to walk away empty-handed. I threw down twenty grand for Zayne. He was battered. Covered in fresh blood and split skin. But his faceit was the kind of gorgeous that stole the air right out of your lungs.
Seraphina found out I bought an Incubus snake and sneered. "Incubus beasts are bottom-tier trash. Zero combat stats. Purely ornamental. Youre going to regret this."
I didn't realize how messed up that warning was back then. Seraphina was my neighbor. We grew up in the same gated community. I was the straight-A valedictorian. The golden child her parents constantly weaponized against her. She was the chronic slacker. The relentless comparisons bred a toxic, simmering hatred inside her.
I ran into her again while stocking up the RV. She was pushing a massive flatbed cart through the wholesale club, loading up a hundred pallets of everything in sight. She side-eyed my meager shopping cart. "That's barely enough for a weekend."
My family owned this big-box retail chain. I didn't need to hoard. I shot back, "What's with the doomsday prep? The apocalypse coming?"
She didn't miss a beat. "Charity drive. Kids in the sticks. I wouldnt expect someone allergic to philanthropy to get it."
The world was perfectly normal then. No red flags. But my gut twisted. I called my parents right there in aisle four and blacklisted her from all our family's retail branches. She had to drive three towns over to finish her hoarding.
Three days into my road trip, the outbreak hit. The world ended. Looking back, Seraphina definitely knew. She bought a top-ten combat beast. She stockpiled a three-year survival bunker. And I? I bought a ridiculously hot snake. My RV pantry held two weeks of food. Tops.
I hardened my heart. I looked over at Zayne. "Zayne. Go check that place. See if there's any food."
"Okay." Zayne didn't hesitate. He popped the RV door and stepped out onto the cracked asphalt, heading toward an abandoned roadside diner.
The second his boots hit the pavement, I slammed my foot on the gas.
The RV engine roared. Tires squealed against the dirt as I sped away.
And right at that exact moment, the glowing chat stream flared across my vision.
Chapter 2
[That roadside diner is infested. Dumping Zayne there is basically murder.]
[My heart breaks for Zayne. Risking infection just to scavenge for Vesper, and she drives off.]
[Vesper is so toxic. Zayne starved himself for her, and she still treats him like a threat.]
[Just because he lacks physical strength right now doesn't mean his combat stats sit at zero.]
[Hes the Thunder-Scale Serpent King. Vesper remains clueless. Zayne levels up through extreme physical intimacy.]
[If she just fed his cravings, hed mutate into the apex predator of the wasteland.]
[Taking his V-card unlocks a pocket dimension. Infinite loot. And shes just handing that massive W to someone else.]
[Plot twist: the actual female lead, Elara, cowers in that diner's root cellar right now.]
[Vesper ditching Zayne literally serves him to Elara on a silver platter.]
[Hes going to become Elara's ultimate meat shield and bankroll her survival with his infinite stash.]
A sharp phantom pain spiked behind my ribs. The air evaporated from my lungs.
Elara. Seraphina's younger sister. Brainwashed by Seraphina's toxic smear campaigns, Elara always had it out for me. Whenever we crossed paths grabbing our Amazon packages off the porches, she looked right through me. Once, my UberEats order ended up at their estate. She fed it to her golden retriever.
When I marched over and confronted her, she offered a sickeningly sweet pout. "Oh, my god, I'm so sorry. I totally thought my sister ordered that for Buster."
"It's fine." I turned away, but not before catching the smug, calculated smirk playing on her lips.
I checked my Uber app later. The driver didn't mess up the drop-off. He drove past their wrought-iron security gate when Elara flagged his sedan down. "That's my order," she demanded. "I messed up the house number. Hand it over."
She wasn't just petty. She was manipulative. A walking red flag. And she was serving as the main character of this twisted doomsday scenario? Seraphina had prepped a three-year bunker. Elara had always carried the ultimate protagonist halo. Both sisters played with actual cheat codes.
The glowing text kept flooding my vision:
[Fact. The sisters own this wasteland.]
[Theyre the main characters. Vesper exists purely as cannon fodder.]
[At the black market, Seraphina planned to bring Elara along.]
[Canon event: Elara buys Zayne.]
[But traffic delayed her. By the time she showed, the auction ended.]
[Seraphina sniped the Direwolf, and Vesper accidentally hijacked Elaras Serpent King.]
[Doesn't matter now. Elara possesses complete plot awareness. Shes about to snatch Zayne right back.]
[You don't just buy a Thunder-Scale Serpent. You bind him by claiming his first time. Vesper never sealed the contract.]
[Elara knows the cheat code. She knows he needs skin-on-skin contact to level up.]
[Without Zayne, Vesper becomes dead weight. Her rations dry up in five days, and Seraphina's Direwolf tears her apart while she scavenges.]
My combat boot slammed onto the brake pedal.
Tires screamed. The heavy Airstream fishtailed, the seatbelt biting hard into my collarbone. I cranked the steering wheel, ripping it to the left. I threw the transmission into reverse and floored the gas, tearing back toward the diner.
Infected bodies burst through the diner's shattered glass doors, thick, dark blood sliding down their rotting jaws.
A piercing, hysterical shriek ripped through the dead air.
I recognized that pitch instantly. It was Elara.
Chapter 3
I scoured the glowing stream for anything useful.
[Did not see Vesper spinning the block. Plot twist.]
[The infected inside the diner are Level One. One-tap kills. But it's a literal horde.]
[She hasn't awakened any abilities yet. Zero combat power. No way she steps out of that Airstream.]
My hands shook on the steering wheel. Zombies. The kind of nightmare fuel reserved for late-night horror flicks. And now, a handful of them swarmed the RV. One clawed its way up the hood. Rotting teeth slammed against the reinforced windshield. Blood smeared across the glass as it let out a guttural shriek.
They looked unstoppable. But the stream called them low-level fodder? One-tap kills?
I gave myself exactly five seconds to panic.
I slammed the gas. The Airstream lurched forward, launching the infected off the hood with a sickening crunch. I ripped a heavy butcher knife from the kitchenette block. I kicked the door open, stepped out onto the asphalt, and yanked it shut behind me.
More infected poured out of the diner's shattered entrance. I tightened my grip on the handle. I charged the closest one, swinging the heavy blade straight for its throat.
The chat lied. It wasn't that simple.
Before the steel even grazed rotting flesh, a vise-like grip clamped around my throat. The butcher knife clattered to the pavement. Blackened nails were a hair's breadth from piercing my skin. Oxygen vanished.
A shadow blurred in my peripheral vision. Zayne exploded from the diner. He gripped a rusted fire axe. The heavy steel cleaved through the infecteds neck in a single, brutal arc.
The severed head hit the ground. My knees buckled. I trembled uncontrollably.
Zaynes hand wrapped around mine. His grip was ironclad, pulling me firmly but keeping me grounded as we headed toward the Airstream. He buried the axe into the skulls of two more infected blocking the steps, then shoved me inside. He turned his back to me. "There are supplies in the diner. I'm going back in."
"Zayne, no!" I choked out, grabbing his sleeve.
He wrenched his arm free and pulled the RV door shut.
The stream immediately lit up.
[Supplies? Try saving Elara. I bet my life on it.]
[He already bumped into Elara inside. Hes not going to just let her die.]
[Does Vesper seriously think jumping out with a kitchen knife undoes everything? Talk about being performative.]
[Way too late for damage control.]
[He literally watched her hit the gas and abandon him earlier. He knows exactly what she is.]
[Once that trust shatters, you can't glue it back together. Major red flag.]
The digital clock on the dash mocked me. Every second stretched into eternity. Thirty minutes passed. The diner remained a black box of silence. Why wasn't he out yet?
The chat flared again: [Zayne is going feral in there. Pure slaughter.]
[Wait for it Once he clears the spawn, an Energy Core drops.]
[Absorb the core, unlock a random ability. Instant power-up.]
[This is exactly why Elara hid in that specific cellar. She memorized the drop locations. She knew Zayne would show up.]
[Sucks for her that Zayne got the last hit.]
[Doesn't matter. Zayne is handing that core straight to Elara.]
Cold dread pooled in my stomach. The air in the RV turned suffocatingly thin.
Through the windshield, I watched thick, toxic black mist bleed out of the diner with every unseen kill. The mist swirled into the sky, condensing rapidly until a jagged Energy Core materialized, dropping perfectly into Zaynes outstretched palm.
Then, the sickening sound of tearing flesh finally stopped.
The diner doors kicked open. Zayne emerged. His clothes were shredded. Fresh blood slicked his skin, masking the pale bruises underneath. He gripped a bloodstained canvas duffel bag in one hand.
He stepped up to the Airstream and rapped his knuckles against the glass. I threw the deadbolt back and yanked the door open. Zayne hauled himself up the steps. His breathing was ragged, his muscles trembling from the sheer physical toll. I reached out to grab the handle and secure the door.
Before the latch could click, a pair of manicured hands pounded against the metal frame.
Chapter 4
The voice belonged to Elara. Recognition flashed in her eyes.
She shoved her shoulder into the doorframe, wedging herself in. "Vesper, please, you have to save me," she whimpered. Her tone dripped with fake desperation, but her eyes kept darting past melocking hungrily onto Zayne in the back.
I didn't hesitate. I dug my nails into her knuckles, prying her manicured fingers off the metal frame one by one. I shoved her back and slammed the door shut.
In the split second before the latch clicked, her pitiful facade shattered. Unadulterated venom flashed in her eyes.
The stream lit up instantly.
[Classic villain behavior. Leaving the main character to die.]
[Chill. Zayne won't just let Elara become zombie chow.]
[Vesper, you might want to check your rearview. Zayne looks murderous right now.]
[Grabbing popcorn. Zayne is totally about to boot Vesper and let Elara take the wheel.]
I spun around, my chest tight. Zayne sat there, his expression unreadable, shadows masking his sharp features. He finally opened his mouth. "Vesper" I braced myself, but his jaw tightened as he issued a single command. "Drive."
"On it." I dropped into the driver's seat, threw the rig into drive, and stomped the gas.
[Bro, Zayne, what are you doing? Major fumble.]
[Since when does Vesper beat Elara?]
I checked the rearview mirror. Elara sprinted after the Airstream, stumbling over the cracked asphalt. "Zayne! Don't leave me!" she shrieked, her voice fading into the dust.
We cleared a mile down the desolate highway.
A massive silhouette barreled toward us from the opposite direction. Seraphina.
Her timing proved everythingshe and Elara definitely coordinated this. Her rig dwarfed my Airstream. It was a heavily modified, armor-plated Skoolie, packed to the roof with her doomsday hoard. The two behemoths scraped past each other on the narrow road.
Through the glass, Seraphinas gaze locked onto mine. Her brow furrowed in sheer disgust.
The Phantom-Eye Direwolf sat rigidly in her passenger seat, radiating lethal energy. She let out a sharp, mocking whistle.
The massive beast snapped its head toward me.
My eyes collided with those unnatural, glowing irises. Pure terror froze the blood in my veins. Cold sweat slicked my palms.
[Start shaking, Vesper. Youre done.]
[Seraphina is going to let that Direwolf rip her throat out.]
[Turn the rig around and hand Zayne over. Maybe the sisters will leave enough of you to bury.]
I slammed the pedal to the floor, putting distance between us. I flicked my eyes to the rearview mirror. Zayne sat hunched over. His broad shoulders hitched with violent tremors. Crimson soaked through his shredded shirt, pooling on the leather upholstery.
I wrenched the steering wheel, turning onto an abandoned mountain access road. I threw it in park near the edge of a sheer drop-off. I bolted for the cabinets, ripping the heavy-duty trauma kit open.
Before I could unscrew the iodine, his large, blood-stained hand wrapped around my wrist. His grip burned against my skin. He pressed the jagged Energy Core into my palm, forcing my fingers closed over it. "Wait," he rasped, his voice rough. "Absorb this first."
"I need to stop the bleeding." I dropped the glowing core onto the counter. I snatched a cotton pad, dousing it in Betadine, and pressed it against a deep gash on his chest.
The chat went supernova.
[Wait, WHAT? Hes giving the drop to Vesper?!]
[Bro, she tried to leave you for dead ten minutes ago! Are you seriously handing her the loot?!]
I wound the white gauze tightly around his torso, my fingers brushing against the hard, feverish heat of his muscles. "Zayne," I choked out, unable to meet his gaze. "Earlier I"
His calloused thumb brushed my knuckle, stopping me. "It doesn't matter." His dark eyes locked onto mine, intense and unyielding. "You came back. That's enough."
He knew exactly what I had planned.
Once I secured the final bandage, he nodded toward the counter, silently demanding I take the core. I picked it up. A vivid, pulsing emerald light bled from the jagged stone, sinking straight into my skin. The light flared exactly three times.
[Holy shit. An SSS-Tier Healing Core.]
[Vesper just unlocked a top-tier healing ability. Pure rigged luck.]
[She just finessed the ultimate cheat code.]
[SSS-Tier means a 3x multiplier on base healing stats right out of the gate.]
[Born on third base and thinks she hit a triple.]
[Doesn't even matter. Healing burns a massive amount of stamina. She'll exhaust herself.]
[This is the apocalypse. Its survival of the fittest. Without raw DPS combat stats, a healer is just a walking target.]
Chapter 5
The Energy Core dissolved into my bloodstream. A surge of crackling electricity rushed through my veins, wiping out every trace of exhaustion.
I focused that raw, buzzing energy into my fingertips and reached for a shallow cut on Zayne's cheek. The split skin stitched itself back together in seconds. Mind-blowing. A massive jolt of adrenaline hit my system.
A healer might be a prime target, but in the wasteland, any ability was a lifeline. I hovered my glowing palms over his remaining, unbandaged gashes. The torn flesh knit closed.
But the stamina drain hit me like a freight train.
My vision blurred. A crushing, leaden exhaustion dragged my eyelids down.
Zaynes large, calloused hand wrapped around my trembling fingers. "Stop," he murmured, his voice a low, rough rumble. "Rest. Let your stamina recharge."
The glowing text flared in my peripheral vision.
[The second Vesper passes out, Zayne is totally dipping to find Elara.]
[Even if he doesn't, the sisters are coming for him.]
[Major heatwave dropping in three days. The surface temp is going to spike to 120 degrees.]
[Zayne is cold-blooded. Skin-to-skin contact with him drops your core temp instantly.]
[He's a walking AC unit. The Airstream is freezing right now.]
[Zero chance Seraphina and Elara let a human AC unit slip through their fingers.]
I couldn't let him leave. Scraping together the absolute last dregs of my strength, I lunged. My weight hit Zayne's chest, sending him crashing backward onto the leather sofa with a dull thud. Heat flooded my cheeks. The air between us instantly thickened, turning stiflingly humid.
"Zayne," I whispered, my voice barely a breath. "Are you hungry?"
"I'm not." His knuckles brushed against the canvas duffel bag wedged beside his hip. The loot from the diner. "Keep the protein bars. You need them."
That wasn't the hunger I meant. If I passed out now, Elara would swoop in and claim his contract. I refused to be a sitting duck. I needed to lock this down.
"Zayne" I breathed out. I leaned down, erasing the last inch of space between us, and pressed my mouth hard against his.
A violent shudder ripped through his rigid muscles beneath my palms. I felt the sudden, frantic spike of his pulse hammering against my fingertips. A low, guttural growl vibrated deep in his chest. He kissed me back, his lips bruising and desperate, consuming all my oxygen. His hands gripped my waist, his fingers digging into the fabric of my shirt.
But my body betrayed me.
The healing burnout was overwhelming. The fire in my blood turned to lead, and the world abruptly faded to black.
Day two.
The sharp hiss of the shower head ripped me out of my sleep. I peeled my eyes open. The stream was already scrolling.
[LMAO, dead. Vesper tried to snipe the contract, but her stamina totally bottomed out. Passed out before she even got a taste.]
[Still, she spent the whole night tangled up with him. His combat stats definitely spiked.]
[He got wrecked by Level Ones yesterday. Today? He could wipe a horde without breaking a sweat.]
[Plot twist: Zaynes V-card is still intact. Elara is still in the game.]
[Zayne has insane self-control. Dude was practically feral last night.]
[Barely made it to sunrise. Boy is in there taking a freezing cold shower to ice down.]
I pushed myself up from the tangled sheets. The bathroom door clicked open. Zayne stepped out, a single white towel slung dangerously low around his narrow hips.
My eyes went completely straight. The man was built like a dark god. My breath hitched.
Water droplets traced the sharp, V-cut lines of his abdomen, sliding down his skin and soaking into the terrycloth. My gaze snagged there. Dropped lower. Urban legends about snake familiars having two suddenly hijacked my brain.
Id never seen one. The curiosity was a sudden, physical itch.
A furious flush crawled up Zaynes neck, burning the tips of his ears. The undeniable, physical tell of his arousal.
[Bros cold shower did absolutely nothing.]
[Is Vesper seriously trying to sneak a peek? Shes unhinged.]
[NGL, I kinda want to know if the snake rumors are true]
[Oh, they're true. 100%.]
Zayne turned, his jaw tight, and stepped into the cramped bedroom to change. He didn't latch the door. He left it cracked open just a sliver.
A silent, electric invitation.
