Living With My Flirty Stepbrother

Chapter Three: The Public Eye

The ten o'clock bell didn’t just signal the start of third period; it signaled the explosion of my digital universe.

I was sitting in the back row of AP Economics, my laptop open under the guise of taking notes on market structures. Exactly as the clock struck 10:00 AM, a synchronized chime went off across the room. Dozens of smartphones buzzed on desks, slipped into pockets, or hid behind heavy textbooks. The official press release detailing the multi-billion-dollar merger between our family empires had just hit the global financial wires—and consequently, every student media outlet at the academy.

"Oh my god," Chloe whispered from the desk next to mine, her eyes glued to her screen. She flashed her phone toward me under the table. The headline from a prominent business blog read: *The Merger of the Decade: Tech and Logistics Giants Form Alliance via Arranged Union of Teenage Heirs.*

Right below the text was a formal photograph of Julian and me from a corporate gala months ago, looking stiff, polished, and untouchable.

Within seconds, the quiet classroom transformed into a hotbed of hushed whispers and darting glances. I could feel the eyes of my classmates burning into the side of my face. To them, I was no longer just the cold, hyper-focused Sierra who ran board meetings before homeroom; I was half of the most talked-about power couple in the country.

I kept my gaze fixed resolutely on the whiteboard, my jaw clamped shut as I forced myself to type random vocabulary words into my notes. *Do not let them see you sweat,* I reminded myself. *You are a billionairess. You handle hostile takeovers for breakfast. You can handle high school gossip.*

"Now, class, if we look at the elasticity of supply..." Mr. Harrison began, completely oblivious to the digital wildfire consuming his classroom.

A shadow suddenly fell across my desk.

I looked up, my defenses instantly sliding into place. Julian had stood up from his seat across the room to turn in a worksheet at the front desk. But instead of walking straight back to his row, he took the long way around, cutting right past my desk.

As he passed, he didn't say a word. He didn't need to. He simply reached out and dropped a small, neatly folded piece of loose-leaf paper onto my open laptop keyboard before continuing down the aisle, his hands casually shoved into his trouser pockets.

My heart did a traitorous, violent flip against my ribs. I looked around quickly, noting that at least five different girls were glaring at the back of my head with pure envy.

With shaking fingers, I unfolded the note beneath the edge of my desk.

*You're staring at the board so hard you're going to burn a hole through it, CeeCee,* his neat, surprisingly elegant handwriting read. *Relax that pretty jaw of yours. They’re just jealous they don't get to marry a genius. See you at lunch. Don't skip—I'm buying.*

I bit the inside of my cheek to suppress the sudden, highly inappropriate smile that threatened to break through my icy exterior. I crumpled the note tightly in my fist and shoved it into the pocket of my blazer, refusing to look across the room at him. If I did, I knew I would catch him smirking, and I wasn't about to give him the satisfaction.

When the lunch bell finally rang, the cafeteria felt less like a dining hall and more like a high-stakes media scrum. The moment Chloe and I walked through the double doors, the ambient noise in the room noticeably dropped by several decibels.

"Just keep walking," Chloe muttered under her breath, keeping her shoulder firmly pressed against mine as we navigated past the crowded tables. "They're like vultures. If you show any weakness, they'll descend."

"I don't do weakness," I replied coldly, lifting my chin and heading toward our usual, semi-private table near the large courtyard windows.

Before we could even sit down, a shadow blocked the light from the windows. It was Alisha, the self-proclaimed queen bee of the senior class, flanked by two of her usual followers. She was holding a tray with a meticulously arranged salad, but her eyes were entirely locked onto me.

"Sierra," Alisha purred, her voice dripping with artificial sweetness. "We all saw the news. A global corporate merger? An arranged marriage? It all sounds so... medieval. I had no idea your family was so desperate for a tech alliance that they had to sell you off to Julian."

Chloe opened her mouth to snap back, but I stood up straight, crossing my arms over my blazer. I let a slow, icy smile touch my lips—the same smile I used when tearing down bad investment proposals.

"It’s called a strategic consolidation of assets, Alisha," I said, my voice cutting through the surrounding chatter with razor-sharp clarity. "I recognize that long-term financial planning might be a difficult concept to grasp when your biggest daily executive decision is choosing a lip gloss, but I assure you, nobody is being 'sold off.' We are simply securing the future."

Alisha’s perfect smile faltered, her cheeks flushing an angry pink as a few nearby students snickered. "Well, let's see how secure you feel when you realize Julian doesn't do 'contracts.' The guy is a professional flirt, Sierra. He’s going to get bored of playing house with a robot within a week."

"Is that so?"

The deep, relaxed voice cut through the tension like a warm knife through butter. Julian stepped into the space next to me, a heavy cafeteria tray balanced effortlessly on one hand. He didn't look angry or defensive; he looked entirely amused, his blue eyes glinting with a dangerous sort of mischief.

Without asking for permission, he set the tray down on my table and slipped his free arm completely around my waist, pulling me firmly against his side. The sudden, intense warmth of his body sent a shockwave straight through my system, but I forced myself to stand my ground, refusing to lean away.

"Because from where I'm standing," Julian continued, looking down at Alisha with an incredibly dismissive, lazy smile, "I think I’m the one trying to keep up with her. Sierra runs circles around most CEOs, let alone high school seniors. So if anyone’s going to get bored here, it's definitely not me."

Alisha opened and closed her mouth like a fish, completely utterly speechless. She gave us both a furious, hateful glare before turning on her heel and storming away, her followers trailing hurriedly behind her.

The moment she was out of earshot, the heavy weight of Julian’s arm disappeared from my waist. I immediately took a step back, trying to catch my breath and ignoring the lingering warmth where his hand had just been resting.

"You didn't need to do that," I muttered, looking down at the tray he had brought over. It was piled with two gourmet chicken sandwiches, a large basket of fries, and two bottles of iced tea. "I can fight my own battles."

"I know you can," Julian said softly, his flirty, arrogant mask slipping away for just a fraction of a second to reveal that genuine, protective warmth I was becoming dangerously addicted to. He pulled out a chair for me, gesturing to the food. "But a good partner covers your flank during a hostile takeover. Now sit down and eat a fry, fiancée. You've had a long morning."

I looked at the food, then at Chloe, who was currently watching us with an expression of pure, unadulterated entertainment. With a defeated sigh, I sat down, pulling a bottle of iced tea toward me.

We were supposed to be an arrangement. A cold, calculated business transaction designed to satisfy our fathers' ambitions. But as Julian sat down across from me, casually stealing one of my fries and flashing me that devastating, lopsided smirk, I realized the cold lines of our corporate contract were completely useless.

The public thought we were a perfect, calculated union. But sitting here in the loud, crowded cafeteria, watching the way his eyes locked onto mine as if nobody else in the room existed, I realized the slow-burn fire between us was becoming entirely too real—and neither of us was trying to put it out.
