Seraphina Croft built a real estate empire, but her fiancé Julian treats her like an ATM—draining her wealth to fund a love nest with his ex in her own Côte d'Azur tower. When she discovers the betrayal, a ruthless billionaire romance unravels, and Julian learns every luxury he enjoys is on loan.

He Bought His Mistress A Penthouse In The Building I Own Summary

Seraphina Croft clawed her way to the top of real estate, but her fiancé Julian sees her as nothing more than a walking ATM. While she closes deals, he uses her black card to build a love nest with his ex, Chloe, inside Seraphina's flagship Côte d'Azur tower. He forges her signature, siphons her fortune into a shell company, and plans a honeymoon with the woman he truly wants. But Julian miscalculated. He didn't just steal from a CEO—he stole from the woman who owns the air he breathes. When the red-header protocol seals the doors and his assets vanish, he'll discover every luxury was a loan from the woman he betrayed.

Chapter 1 of He Bought His Mistress A Penthouse In The Building I Own

My fiancé charged a $4.2 million penthouse to my credit card—in the building I own—for his mistress.

"It's our wedding gift, Sera," Julian laughed, his hand lingering on Chloe's hip as they toasted with my vintage champagne.

The marble floors they planned to tear out were mine, and the future they were stealing was built entirely on my bank account.

He thinks he's a genius playing a weak woman, but he has no idea that one click from my laptop will erase his entire life.

****

The phone screen lit the dark bedroom like a struck match. $4,200,000.00 USD. Merchant: Côte d'Azur Estates. I read the number twice before the whiskey in my hand even registered as cold.

I sat on the edge of the mattress, a heavy crystal tumbler in my left hand. I lifted the glass. The whiskey burned a harsh, fiery path down my throat. Good. I needed the sting. It kept my mind sharp.

I tapped the speed dial for my wealth manager.

"Elias," I said the second the line connected.

"Seraphina. I was just about to text you. The fraud alert just hit my terminal."

"It is not a stranger."

"Julian?"

"Julian." I kept my eyes fixed on the shadows in the corner of the room. "Cancel the transaction immediately."

"Impossible. He used your VIP bypass code. The funds bypassed the standard holding period."

"He used my personal code to buy a penthouse in my own building."

"Technically, Vanguard Real Estate owns the building, and you own Vanguard. But yes. He bought the Unit A Penthouse. The crown jewel of the project."

"Reverse it, Elias."

"The escrow is fully digital. Once the biometric clears, the money sits in Vanguard's corporate accounts. You will have to void the contract from the seller's side. If I try to pull it back from the bank's end, it triggers a federal audit."

"How did he get the bypass code?"

"It requires dual authentication. He used the supplementary card and the master PIN you set up for the joint wedding accounts."

"He drained the wedding reserve for this?"

"Every cent. Plus a three-million-dollar overdraft on your primary line of credit."

"Watch me handle this." I ended the call.

I dialed Julian's number. He answered on the second ring. Laughter echoed through the speaker. A woman's laugh. High, grating, and entirely too familiar.

"Sera! You are up!" Julian's voice spilled over with fake, exaggerated cheer.

"Four point two million dollars, Julian."

"I knew you would get the alert. Surprise!"

"Explain the surprise. Quickly."

"It is our wedding gift. The Côte d'Azur penthouse. The one with the wraparound balcony you showed me last month. We are moving in before the ceremony."

"You bought a property from my company, using my money, to gift to me."

"It is marital assets, Sera. We are signing the papers in three weeks anyway. I just wanted everything ready. The broker opened the office late just for us."

"Us." I repeated the word, tasting the foulness of it. "Who is laughing in the background?"

"Oh, Chloe is here."

"Your ex-girlfriend is helping you buy my wedding gift."

"She is an interior designer, Sera! Stop being so paranoid. She helped me pick the imported marble for the master bath. You have been so busy with the merger, I wanted to take this off your plate."

"Sera, you make eight figures a year," Julian continued, his tone shifting to something defensive. "Four million is nothing to you. Why are you acting like I stole from you?"

"Because you did. You used the wedding reserve."

"It is an investment! Real estate always appreciates. Plus, Chloe negotiated a five percent discount with your broker."

"She negotiated a discount on my property, with my broker, using my money."

"See? You are doing that thing again. You are making it about control."

"Put her on."

"What? No, we are celebrating."

"Put Chloe on the phone, Julian. Now."

Rustling. A muffled whisper. Then, a sweet, cloying voice.

"Hi, Seraphina! Oh my god, the view up here is stunning. You are going to love the soaking tub I picked out for you guys."

"Hand the phone back to Julian."

"I just wanted to say congratulations. Julian was so stressed about finding the perfect place, and I told him, why not buy the best unit in your own building? It keeps the money in the family, right?"

"Hand it back."

More rustling. Julian cleared his throat. "There. Are you happy? You always have to make things so tense."

"Are the physical contracts signed?"

"Just finished. We are waiting on your site manager to print the final deed."

"Enjoy the view, Julian."

"We are. I will see you at home."

"Do not bother." I ended the call.

I set the whiskey glass down on the nightstand. The ice settled with a sharp clink. I tossed the duvet aside. The hardwood floor felt like ice against my bare feet. I crossed the room in quick strides and reached the mahogany desk, flipping open my encrypted laptop.

The screen flared to life, illuminating the dark corners of the room. I tapped my earpiece, dialing the site manager.

"Marcus. Report."

"Ms. Hale. I am sorry to bother you so late, but Mr. Voss insisted on the VIP walkthrough."

"I know. I am looking at the charge."

"I have the final deed queued up. He is asking for the keys."

"Do not print that deed."

"Ms. Hale?"

"You heard me. Halt the printing."

"He is standing right outside the glass. He has a bottle of our vintage Dom Pérignon open. He and Chloe are toasting to the new master bedroom."

"Let him drink it. It is the last thing he will get from me."

"Ms. Hale, he is currently measuring the living room floor with Chloe. They are talking about tearing out the Italian hardwood we just installed last week."

"Tearing it out?"

"Chloe says it clashes with her vision for your feng shui."

"My feng shui."

"Yes, ma'am. Should I call security?"

"Not yet. Let them finish their champagne."

"If I stop the deed process now, the system will flag the transaction as incomplete. It triggers the security protocol."

"I built the protocol, Marcus. I know what it does."

"It will freeze the entire Côte d'Azur project. All sales, all transfers, all escrows. The board will be notified instantly."

"Let the board panic. I will handle them tomorrow."

"Julian is going to throw a fit. He is already telling the sales staff he is taking over the penthouse renovations tomorrow morning."

"Julian is about to learn what happens when you play with my money. I am logging into the executive intranet now."

"Awaiting your command, boss."

I typed in my master password. The Vanguard Real Estate portal loaded.

My spine snapped perfectly straight. The leather office chair groaned under the sudden shift in weight. I grabbed the wireless mouse and squeezed the plastic shell hard enough to make the joints pop.

The screen displayed the Côte d'Azur master ledger. Right at the top: Unit A Penthouse. Status: Pending Final Generation.

I moved the cursor to the top right corner.

A solid red button dominated the screen.

"One-Click Freeze Project."

My index finger hovered over the mouse. Three millimeters. That was all the distance left between Julian's smug celebration and total, catastrophic ruin.

He had no idea whose name sat on the building's holding certificate. He had never once thought to ask.

I pressed down.
