Aria Morgan adjusted the strap of her leather tote bag, her fingers trembling slightly as she stepped into the sleek, glass-walled lobby of Blackwood Enterprises. The air smelled of ambition and expensive cologne, and the hum of productivity buzzed around her like a live wire. She had dreamed of this moment for years - landing an internship at one of the most prestigious marketing firms in the city. But now that she was here, her stomach churned with a mix of excitement and dread.

She glanced at her reflection in the polished elevator doors. Her tailored blazer and pencil skirt screamed professionalism, but her unruly auburn curls betrayed her nerves. *You belong here,* she reminded herself, straightening her posture. *You earned this.*

The elevator ride to the 30th floor felt like an eternity. When the doors slid open, she was greeted by a sprawling open-concept office filled with the city's brightest minds. Her new supervisor, a no-nonsense woman named Claire, greeted her with a brisk handshake and a stack of paperwork.

"Welcome to Blackwood Enterprises," Claire said, her tone clipped but not unkind. "You'll be shadowing the senior team on the new Luxe Cosmetics campaign. And just so you know, Mr. Blackwood likes to personally vet all new interns. He'll be expecting you in his office at noon."

Aria's heart skipped a beat. "Ethan" Blackwood. The name alone was enough to make her palms sweat. He wasn't just the CEO of Blackwood Enterprises; he was also the overprotective older brother of her best friend, Sophie. And if their past encounters at family gatherings were any indication, he wasn't exactly her biggest fan.

The memory of their last meeting flashed in her mind - Sophie's birthday dinner, where Ethan had cornered her in the kitchen, his piercing green eyes narrowing as he grilled her about her career plans. "Marketing?" he'd said, his voice dripping with skepticism. "It's a cutthroat industry. Are you sure you can handle it?"

Aria had fired back with equal venom, refusing to let him intimidate her. But now, standing in his domain, she couldn't help but feel like she was walking into the lion's den.

At precisely noon, she knocked on the door to Ethan's office. His deep, commanding voice called out, "Come in."

She pushed the door open and stepped inside, her breath catching at the sight of him. Ethan Blackwood was every bit as imposing as she remembered. His tailored suit clung to his broad shoulders, and his dark hair was perfectly styled, not a strand out of place. He sat behind a massive mahogany desk, his sharp features illuminated by the sunlight streaming through the floor-to-ceiling windows.

"Aria," he said, his tone cool and measured. "Take a seat."

She obliged, crossing her legs and folding her hands in her lap, determined to project confidence. But Ethan's gaze was like a laser, cutting through her carefully constructed facade.

"Let's get one thing straight," he began, leaning back in his chair. "This internship isn't a favor to Sophie. If you're here, it's because you earned it. But make no mistake - I won't go easy on you just because you're her friend."

Aria bristled at his tone but kept her voice steady. "I wouldn't expect you to, Mr. Blackwood."

His lips twitched, almost imperceptibly, at her use of his formal title. "Good. Because this isn't a playground. It's a battlefield. And if you can't keep up, you'll be out before the end of the week."

The challenge in his eyes ignited a fire in her chest. She leaned forward, her own gaze narrowing. "I didn't come here to play games. I came here to prove myself. And if you're worried I'll embarrass you, don't be. I'm more than capable of holding my own."

For a moment, the room was silent, the tension between them crackling like static. Ethan studied her, his expression unreadable. Then, to her surprise, a faint smirk tugged at the corner of his mouth.

"We'll see about that," he said, standing abruptly. "Claire will show you to your desk. Don't be late tomorrow."

Aria rose to her feet, her pulse racing. As she turned to leave, she couldn't resist one last jab. "Don't worry, Mr. Blackwood. I'll be here bright and early. Wouldn't want to give you an excuse to doubt me."

His low chuckle followed her out the door, sending a shiver down her spine. She didn't know whether it was a sign of respect or amusement, but one thing was clear: Ethan Blackwood wasn't just her boss. He was her biggest challenge.

And she was ready to rise to it.

As she walked back to her desk, Aria couldn't shake the feeling that this internship was about to become so much more than she'd bargained for. The sparks between her and Ethan were undeniable, and if their first meeting was any indication, the next few months were going to be anything but ordinary.

Little did she know, the real battle - and the real attraction - was just beginning.
