Reborn to Tempt My Ex's Best Friend

Serena's POV

The Pacific stretched out in cold, merciless gray-blue at dawn, like an endless mirror reflecting my exhausted, disheveled state. I sat on the Santa Monica sand, phone propped against a weathered piece of driftwood, the red recording light flashing steadily—like the last stubborn spark I still had left.

"So…" I took a deep breath, trying to keep my voice calm. "This is the part where I'm supposed to tell you everything will get better, right?"

The wind carried a salty chill across my face. Dad used to bring me here when I was eight. He would roll up his sleeves, kneel in the tide pools, and teach me to name the tiny creatures clinging to life among the rocks. "The ocean doesn't care how small or fragile you are, Serena," he'd say with that warm, steady voice. "It only cares if you learn to survive." Those mornings smelled of salt and hope. Now the same ocean just reminded me how easily everything could be swept away.

"My father, Dr. Nathan Reed, is dying. Pancreatic cancer, stage four. The bills at UCLA Medical Center…" I forced a bitter smile. "They don't give discounts just because your dad was the man who built the Reed Marine Institute into what it was—a legacy three generations of marine biologists dreamed of creating. They want their money, and they want it now."

I hugged my knees tighter, my fingers pressing into the cold, damp sand until it hurt.

Mom is in prison—serving five years for research fraud and financial mismanagement. Charges that were supposed to fall on my dad instead. He was the principal investigator and legal head of the institute, but Mom signed off on the financial reports and took the legal responsibility when everything collapsed. She took the blame so he could stay out of prison while he’s dying, instead of spending whatever time he has left locked up while investigators tore through everything he built.

The Reed Marine Institute—three generations of work, research trips, published studies, all of it—was shut down overnight. Assets frozen. Reputation destroyed.

Everything my family built… gone, like it never meant anything at all.

And the person who dragged me into this abyss was Jax Thornfield.

I once thought he was my salvation. Four years ago, he had walked into my life at a beach bonfire, all easy smiles and sun-bleached hair, promising he would stand by me when the world was falling apart. When Mom was arrested and Dad got his diagnosis, Jax was the one who held me while I cried. He was the one who said, "We'll figure this out together."

Instead, he and my best friend Anna dug a beautiful trap together—OnlyFans. They swore it would be nothing explicit. "Just fitness and lifestyle content," they said. "You'll still look classy. We'll control the narrative." They made it sound so simple, so noble. Enough to keep Dad's chemo going. Enough to keep the lights on. Enough to stop me from drowning.

I believed them because I was desperate. Because when you're watching your father waste away in a hospital bed, you don't ask too many questions. You just grab the hand that reaches out.

I picked up the strawberry cake box and the bouquet of California poppies I had bought at dawn. The bright orange petals trembled in the wind, fragile and beautiful, just like the hope I was still trying to hold onto.

"Today is my twenty-second birthday. Yet here I am, carrying a cake and flowers to surprise the boyfriend who's 'too busy helping me.' Because he's working so hard for us, right?" My voice cracked on the last word, and I knew I was lying to myself. The doubt had been growing for weeks—the way he avoided my eyes, the late nights that didn't add up, Anna's sudden distance masked by overly bright texts. But I wasn't ready to face the truth yet. I needed to see it with my own eyes, needed to give this relationship one last chance to prove my paranoia wrong, even though every instinct screamed that I already knew what I would find. I ended the recording and saved it to my hidden drafts folder, where all the versions of myself that the world could never see were kept.

The drive back up the Pacific Coast Highway felt endless. My ancient Honda Civic rattled over every crack in the road. Cheerful pop songs played on the radio, singing about summer love and endless possibilities while I white-knuckled the steering wheel. At a red light, I checked my reflection. The concealer did nothing to hide the dark circles anymore. Three all-nighters editing "tasteful" content—posed yoga flows at sunrise, carefully cropped bikini shots—had left permanent shadows under my eyes.

My phone buzzed. First it was the usual notification from my OnlyFans DMs. I sighed, already knowing what it would be before I even tapped it open. Another unsolicited nude from some random “fan,” accompanied by a bunch of crude messages: “Come serve me, you dirty girl,” “I get so hard seeing you,” “Send something back or I’ll spread your pics.” The words barely registered anymore. I’d grown numb to it months ago—strangers and so-called supporters sending this kind of garbage every day like it was normal. Delete. Block. Move on.

Only then did I check the other message. Anna: Tonight free? Sorority reunion thing. Come through, babe.

I typed back quickly: Working late. Won't be home.

Her thumbs-up reply came instantly. I told myself it was nothing. I had been telling myself a lot of things lately.

The apartment building smelled like old carpet, fried food, and quiet desperation. I climbed the three flights of stairs with the cake and flowers, heart beating too fast. Mrs. Kowalski was watering her geraniums as usual, her apron dusted with flour.

"Serena, darling! You're back early. I just baked an apple pie—want some?"

I forced a smile. "Maybe later, Mrs. K. I'm surprising Jax. It's my birthday and… he's been working so hard for us lately."

Her face lit up with genuine warmth. "Happy birthday, sweetheart! You two are adorable. Go on, don't keep him waiting!"

Her kindness almost broke me. She was the only person in this building who still looked at me like I was the same girl from the Institute, not the one secretly running an OnlyFans account.

I reached our door, keys in hand, still wearing that fragile smile. Then I heard it.

A low, guttural groan. Jax.

Followed by a breathy, all-too-familiar moan that turned my stomach to ice.

Anna.

The keys slipped from my fingers and clattered loudly on the floor. For one long, cowardly second, I considered turning around and running. Instead, my trembling hand turned the knob.

The open-layout apartment offered no mercy.
