A BILLIONAIRE'S SECRET

October in Brookedge was no time for a heatwave, but that didn't stop the sun from rising like it had a grudge, turning the pavement into a skillet by noon. Mornings were the only reprieve, quiet and cool brief pockets of calm before the burn.

Callie Reyes was already in the kitchen, flipping eggs while the rest of the apartment slept.

She slid breakfast onto plates, wiped her hands, and grabbed her envelope, the one with her ID and birth certificate, then slipped out the door without a sound.

Last night's words echoed in her head, still sharp:

"Mia, I'm done playing host. Two grand a month is not charity, but it is not covering her half either. She's practically living here rent-free."

That was her brother-in-law, again. Same fight. Louder this time.

Callie didn't belong there anymore. But leaving without a plan would only make her sister worry.

So she made one. A big one. Marriage.

It wasn't romantic. It wasn't even about love. It was about peace. For everyone.

She had once helped a woman in a parking lot, Mrs. Halston after she had almost fell from the slippery ground. They stayed in touch, and Callie came to know all about her grandson, Theo, a corporate shark who avoided relationships like a second job.

Mrs. Halston had brought it up weeks ago: "You need stability, and my Theo needs someone who won't play games. Think about it."

And now, here she was, at City Hall, breathing hard through her nerves.

''Callie!"

She turned. There stood Mrs. Halston, all smiles, waving like they weren't about to do something absurd. Beside her stood Theo, silent, hands in his pockets, watching her like he was trying to figure out what kind of mess she might be.

"That's him," Mrs. Halston said, proudly. "My grandson. Don't let the scowl fool you."

Callie walked over. Theo was tall, sharp, and gave off the vibe of someone who measured people before speaking to them. She expected someone plainer and definitely less... composed.

He didn't offer a smile, just a small nod.

"Callie Reyes," she said, holding out her hand.

He shook it, firm and quick. "Theo."

She glanced at the modest car behind him. Nothing flashy. Clean and responsible. Not what she expected from someone with an executive title at Cordon Dynamics.

"I told you," Mrs. Halston went on, "he's got a good job, stable, clean..." she elbowed Theo, "...and only slightly allergic to human interaction."

"I'm standing right here," Theo muttered.

Callie tried not to laugh. "It's fine. I'm not great with people either."

Mrs. Halston clapped her hands. "Perfect! Go inside. I'll wait out here."

"It's hot," Theo said. "You should sit in the car."

He opened the passenger door for his grandmother with surprising care. That gesture was simple and unspoken, it told Callie everything she needed to know.

This was definitely not about romance, but neither was she signing up for cold indifference either.

He turned to her. "Let's get this over with."

"Wow," she said. "You sure know how to sweep a girl off her feet."

His mouth twitched. Maybe the closest he ever got to a smile.

Inside, as they waited for the clerk to process their documents, Theo looked at her with those unreadable eyes.

"You're still free to walk away, you know. I won't hold it against you. If this feels rushed, say the word."

Callie folded her arms, steady. "Is this you giving me an out, or hoping I'll take it?"

He didn't answer right away. "Maybe both."

She nodded slowly. "Well... I'm here. Let's just take the plunge."

It usually takes Callie a few days to think things through, but once she makes a decision, she sticks to it. This marriage wasn't something she planned lightly, talk less one of convenience. So, when the clerk asked them if they were sure, she gave a confident nod.

Theo did not say anything, just took out his ID and placed it on the desk. Callie followed suit. Ten minutes later, they were officially married.

Theo turned to her, already reaching into his pocket. "Here, these are the keys to the apartment. It's in Brookedge Heights, near the West End station. You're only ten minutes from your bookshop by bus, maybe five if the traffic is light."

Callie turned the keys over in her hand, quietly absorbing the surreal weight of what they had just done.

"I assume you have a license?" he continued. "If you decide you want a car, I'll front the down payment. You also do not have to worry about the monthly instalments. My company will have that handled, it makes the commute easier, but, your call."

He was not exactly warm, but he was strangely... methodical. Like he had thought of everything and was just running through a checklist.

"I'll be gone a lot," Theo added. "Work is demanding. Business trips. Late nights. I'll transfer household funds, basically wifely allowance to your account on the tenth of each month... should be enough for whatever you need."

He paused before adding, "Also, I think it would be better if we kept this quiet, for now. Saves complications."

Callie blinked, trying to keep up with the wave of logistics. "So... this is your usual post-nuptial speech?" she said with a half-smile.

Theo glanced sideways at her, his expression unreadable. "Just trying to be clear."

"Well, I appreciate the honesty," she replied. "And yes, I've got a license, but I ride an e-bike to work. Just upgraded the battery last week. Feels like a waste to park it."

He didn't argue.

"By the way," she added, "are we... splitting costs?"

He raised an eyebrow. "Huh''. He looked extremely perplexed like he had never heard such absurdity in his life.

"I'm not looking to mooch off you," Callie said simply. "We don't know each other. It just feels fair."

Theo shook his head. "I can afford to take care of my household. That includes you. I would not have married you if I didn't plan on doing things properly."

There was a beat of silence. Callie nodded, quietly impressed by how direct he was.

"Alright then," she said. "But I'll still chip in where I can." The independent woman persona in her was rearing its head high today.

He checked his watch. "I've got to get back to the office. You can take my car, or grab a cab, I'll cover it whichever way you are comfortable. I'm dropping my grandmother off at my brother's."

Callie reached for her phone. "Let's exchange numbers, at least. Just in case."

They swapped contacts. "Thanks, but I'll call a cab. Go do your... things."

He reached into his wallet, pulled out a couple of bills, and offered them to her.

"I'm fine," she said quickly. He just stared at her until she took the money.

Theo didn't wait around for goodbyes. He strode ahead, leaving City Hall alone.

Outside, Mrs. Halston was already waiting, her eyes narrowing as Theo approached solo.

"Where's Callie?"

"She's heading home," Theo said, buckling his seatbelt and pulling out the marriage license to show her. "We signed everything. I gave her money for a cab."

"She just became your wife, Theo. Do you think that's how husbands act? What's wrong with walking her out at the very least?"

"I've got a meeting in twenty," he replied flatly. "You wanted me to marry her. I did. But how I manage this going forward is up to me."

He glanced at his grandmother. "If this turns out to be a mistake, I won't drag it out. But if she's the real deal... I'll know soon enough."

Mrs. Halston scoffed. "You sound like you're interviewing a candidate, not marrying a woman."

Theo started the car.

She sighed, shaking her head. "Just so you know, divorce is not an option in this family."

"That depends on whether you picked someone worth sticking with."

The car rolled forward. After a few quiet minutes, Theo pulled over at a nearby intersection, where a row of black sedans waited, one of them a sleek Rolls Royce.

He stepped out and handed the keys to a waiting driver. "Take her home."

"I'm not going back," Mrs. Halston huffed, crossing her arms. "I want to spend time with my granddaughter-in-law."

Theo didn't even flinch. He opened the door to the Rolls, stepped in, and shut it without another word. A moment later, the car pulled away.

Mrs. Halston stood there on the curb, fuming. "Heartless brat!"

Then, with a huff, she pulled out her phone and dialled Callie.

Callie answered on the second ring, watching traffic pass outside the cab window.

"Hey, sweetie. Theo didn't mean anything by leaving like that. He's just drowning in work," Mrs. Halston said gently.

Callie let out a breath. "It's okay. I'm not bothered. He covered the fare and gave me the keys. I'm on my way home."

There was a pause. "You know... you're married to Theo now. Are you still going to call me 'Mrs. Halston'?"

Callie smiled faintly. "Well, we would see in due time, I'm not really used to the theatrics of all these yet"

"Oh, alright I understand, you'll start calling me Gran before you know it, that would be much better." Her tone turned bright and warm.

"We're family now," she said proudly. "And if Theo ever gives you grief, you come straight to me. He may run half the city, but I still scare the pants off him."

Callie laughed softly. She wasn't sure what she'd just gotten into, but at least she wasn't in it alone.

Callie stood in the middle of the new apartment, surrounded by boxes that weren't hers.

The place was too clean. Not in a bad way, just... impersonal. Like someone had money and let a designer go wild without ever actually living there. The floors gleamed, the furniture was modern, and the kitchen looked untouched.

She placed her canvas bag on the kitchen island and glanced around. One hallway led to what she guessed was the master bedroom. Another, smaller door probably led to the guest room. Or a storage closet. Hard to tell.

Everything about Theo's apartment screamed "minimalist on a schedule." Not a photo frame in sight. Not even a coat hanging near the door.

Callie wandered into the bedroom and froze.

The bed was massive. King-size, crisp grey sheets, and not a wrinkle in sight. One side of the closet was packed with suits and dress shirts-all perfectly arranged by colour. The other side? Empty. Waiting.

Her side, apparently.

She dropped onto the bed and stared at the ceiling. For the first time since signing the papers, it really hit her: she was married.

To a man she barely knew.

To a man who probably spent more time with his phone than with people.

The apartment was nice. Too nice. Which made her feel out of place in her scuffed sneakers and thrifted jeans.

She glanced at the clock. 4:12 PM.

Her shift at the bookstore didn't start until six, so she pulled out her phone and called Mia.

Her sister didn't answer.

Of course.

Callie hung up and shot a quick text "I moved out. Don't worry about me anymore, I'm safe. I'll explain soon."

The second it sent, her phone rang.

She didn't even look at the caller ID. "Mia-"

"Is it true?" came Mia's voice, sharp with disbelief. "You left this morning and did not say a damn word? Where are you? Whose name is on that text plan now-Callie, are you crying?"

"I am not crying," she lied, swiping at her face. "And yes, I moved. It was time."

"You can't just vanish, Callie! I have been worried sick all day. You should have discussed it with me first"

"You made it clear I wasn't welcome anymore," she said, trying to keep her voice even.

There was silence on the other end.

"I'm not mad," Callie added, more gently this time. "I just... I figured something out. I have a place now. A good one."

Mia let out a slow breath. "And what, it just fell into your lap?"

"Something like that."

Callie didn't elaborate. She knew how it would sound.

After they hung up, she lay on the bed for a few more minutes before finally peeling herself up and heading for the kitchen. She needed something to do, anything to stop her brain from spiralling.

She found the pantry half-stocked. Enough to make something decent.

As she boiled pasta and threw together a quick sauce, when a soft ding echoed from her phone.

Unknown number: "Don't get too comfortable. I'm coming home early tonight."

She blinked at the message, rereading it twice.

Theo.

Apparently, he didn't bother saving his number under a name.

By 6:47 PM, Callie was in the bookstore, restocking the poetry shelf when her coworker, Jenna, slid in beside her with an elbow to the ribs.

"You look suspiciously well-fed today. New moisturizer? New man?" She winked

Callie snorted. "Definitely not a man."

"Shame," Jenna replied, dragging out the word like it hurt her. "Because that energy you're radiating? That's married-woman-who-finally-slept-on-1200-thread-count-sheets energy."

Callie turned to face her, amused. "That's a very specific category."

"I know my linens."

They worked the rest of the evening in relative silence, save for the occasional customer question or recommendation debate. Callie liked her job. It was quiet, familiar. Books didn't ask questions. They didn't look at her like they were trying to solve her.

She got home just after ten, and Theo was there. Not in a suit. Not on his laptop, but on the couch. In sweatpants...barefoot.

He was drinking tea and reading a legal document like it was light entertainment. He then looked up when she stepped in.

"You left the second lock undone."

"Hello to you too," she said, kicking off her shoes. "Didn't realize we had a curfew."

"We don't. But safety isn't optional."

Callie raised an eyebrow. "And here I thought you'd be out schmoozing billionaires over overpriced cocktails."

He didn't respond immediately, just folded the paper and set it on the table.

"I got bored."

"Of billionaires?"

"Of people pretending to be interested in what I do."

There was something weary in the way he said it, like someone who had spent one too many hours nodding at small talk.

Callie moved toward the kitchen. "I made pasta earlier. There's some left if you want."

He looked mildly surprised. "You cooked?"

"It's edible, I promise."

He stood and followed her in. "I figured you'd order takeout."

"Just because I married into money doesn't mean I've forgotten how to boil water."

He leaned against the counter, arms crossed, watching her move. She pulled out the container, popped it in the microwave, and ignored the way his eyes tracked her.

"You always this... prepared?" she asked.

Theo blinked. "What do you mean?"

"You had an apartment, a plan, spare keys, and a whole speech ready. Makes me think this isn't your first fake marriage."

He gave a quiet snort. "No. But I'm good at making things run smoothly."

Callie didn't say anything. Just nodded as she plated the food.

"You are definitely not what I expected," he added after a moment.

She glanced at him. "What did you expect?"

"I don't know. Someone louder. More demanding. Maybe someone who'd ask for designer bags by week one."

She shrugged. "I just want a place to breathe."

He nodded like he understood that more than he let on.

They ate in relative silence, side by side at the kitchen island.

Afterward, Callie gathered the plates and washed them without being asked. Theo offered to help. She refused. It was easier to do than to talk.

But before she left for the bedroom, he called out softly.

"Callie."

She turned.

"If this gets weird, or uncomfortable, or if you change your mind, tell me."

It wasn't an apology. Not exactly. But it was something.

Callie met his eyes. "Same goes for you."

Then she disappeared down the hall, leaving Theo staring at the clean kitchen, wondering how a stranger could make his house feel less empty in a single day.
