Rose forced her expression into neutral lines as she turned back to the whiteboard, erasing the incorrect equation with sharp, deliberate strokes. The chalk dust seemed to mock her, floating in the morning light like evidence of her mistake—her very public, very humiliating mistake.

"You're absolutely correct, Mr...?" She let the question hang, though she knew exactly who he was. Every inch of him was burned into her memory like a brand she couldn't escape.

"Andrew. Billy Andrew." His voice carried that same confident warmth that had undone her last night, but now it felt like a challenge thrown across the classroom, a gauntlet dropped at her feet.

"Mr. Andrew." She wrote the corrected equation on the board, her handwriting more precise than usual, each number and symbol a small act of defiance against the chaos he'd introduced into her ordered world. "Thank you for catching that error."

The classroom buzzed with whispered amazement. Students exchanged glances, phones discretely angled to capture the moment—someone had actually corrected Professor Carter and lived to tell about it. Rose could feel their eyes on her like physical weight, waiting to see if the legendary Ice Queen would crack under pressure.

She wouldn't give them the satisfaction. She couldn't afford to.

"As Mr. Andrew correctly identified, when we apply L'Hôpital's rule to this function..." Rose launched into the explanation with renewed intensity, her voice cutting through the room like a blade through silk. She worked through three more problems without pause, her pace relentless, almost punishing.

The students scribbled frantically, trying to keep up with her accelerated tempo. Pens scratched against paper, pages rustled, someone's calculator clattered to the floor. All except Billy, who leaned back in his chair with that infuriating half-smile, watching her like she was performing for his private entertainment.

*Focus*, Rose commanded herself, but her traitorous mind kept drifting. The way his eyes tracked her movements reminded her of how he'd watched her in the hotel mirror, how his gaze had followed every curve of her body as she'd moved above him in the darkness. The memory sent an unwelcome flush of heat through her, and she pressed her lips together, forcing herself to concentrate on the calculus.

When she glanced his way again, Billy had the audacity to nod appreciatively, as if praising her recovery. The gesture was so subtle that no one else would notice, but Rose caught it, and it made her blood sing with fury.

Her jaw tightened. Two could play this game.

Rose selected the most complex problem from her mental arsenal—a multi-layered integration that typically took her graduate students twenty minutes to solve. If Mr. Andrew wanted to show off, she'd give him a platform worthy of his apparent confidence.

"Mr. Andrew, since you're so attentive today, perhaps you'd like to solve this next equation at the board?"

A collective intake of breath filled the room. Several students actually gasped. Being called to the board by Professor Carter was usually a death sentence—a public execution designed to humble overconfident students and serve as a warning to the rest. Rose had perfected the technique over years of teaching, watching cocky undergraduates crumble under the pressure of her impossible problems.

Billy's smile widened, and Rose caught a glimpse of something predatory in his expression. "I'd be delighted, Professor."

He rose from his seat with fluid grace, and Rose caught herself noticing the way his navy shirt stretched across his shoulders as he moved, the confident set of his spine. Her mouth went dry as she remembered how those shoulders had felt under her hands, how they'd flexed as he'd moved within her.

*Stop it*, she commanded herself, forcing the memory away. She focused instead on the satisfaction she'd feel when he stumbled over the deliberately complex problem she'd chosen. This would put him in his place, remind him—and the rest of the class—exactly who held the power in this room.

But Billy didn't stumble. His handwriting was confident as he approached the whiteboard, taking the chalk from her fingers with a brief contact that sent electricity shooting up her arm. Their eyes met for a fraction of a second, and she saw something that made her stomach flutter—not nervousness or intimidation, but anticipation.

He worked through the equation with methodical precision, each step building logically on the last. Rose watched in growing dismay as he navigated the complex integration, his movements economical and sure. When he reached the solution, he paused, studying his work with the same focused intensity she'd seen on his face in the hotel room.

Then he did something that made her heart stop. Billy offered an alternative approach—a more elegant solution that bypassed two of the more tedious steps. It was brilliant. It was exactly what she would have done.

"Excellent work," Rose said through gritted teeth, the words tasting like ash in her mouth. "You may return to your seat."

As Billy walked back to his desk, Rose heard the whispered conversations rippling through the classroom like wildfire.

"Oh my God, he's actually keeping up with her."

"Did you see that alternative method? That was genius."

"Who is this guy?"

A girl in the front row—Sarah, one of Rose's more dedicated students—leaned toward her neighbor. "I've never seen anyone handle Professor Carter's impossible problems like that. He made it look easy."

Rose's control frayed at the edges like a rope under too much tension. She'd intended to humiliate him, to establish the hierarchy that his very presence threatened. Instead, she'd given him a platform to shine, and now half the class was looking at him with newfound respect—the same respect they'd once reserved for her alone.

The remaining twenty minutes of class dragged like hours. Rose taught with mechanical precision, her mind churning with frustration and something dangerously close to admiration. Every time she looked at Billy, he was watching her with that same attentive expression, occasionally jotting notes with the focused concentration of a student genuinely engaged with the material.

It was maddening. It was attractive. It was everything she couldn't afford to feel.

When the bell finally rang, the sharp sound cutting through the tension like a knife, Rose busied herself organizing papers with unnecessary precision. Students began filing out, their conversations a buzz of excitement about the morning's unprecedented drama.

"Did you see how calm he was when she called him up?"

"I can't believe someone actually corrected her equation and lived to tell about it."

"He's kind of hot, isn't he? In that mysterious, dangerous way."

"Do you think something's going on between them? The tension was crazy."

Rose's hands stilled on her lesson plan, her blood turning to ice. She could feel Billy's presence like heat at her back, could sense him lingering while the classroom emptied of students. The last few stragglers gathered their belongings with unusual slowness, clearly hoping to witness whatever came next.

"That's all for today," Rose said crisply, not looking up from her papers. "Please review chapter twelve for Wednesday's class."

The final students reluctantly filed out, leaving whispered speculation in their wake. When the last one disappeared into the hallway, silence settled between Rose and Billy like a loaded weapon, heavy with unspoken tension and dangerous possibilities.

"Quite the performance, Professor."

Rose didn't turn around, didn't trust herself to look at him. "I don't know what you mean."

"The way you called me to the board. Very clever." His footsteps approached slowly, each one echoing in the sudden quiet of the empty classroom. "Though I have to say, I expected something more challenging from someone of your reputation."

Now she did turn, her eyes flashing with anger and something else she refused to acknowledge. "My reputation?"

Billy stood three feet away, close enough that she could see the gold flecks in his blue eyes, close enough to catch the faint scent of his cologne—the same scent that had lingered on her skin this morning. Close enough to remember how those eyes had looked in the dim hotel lighting, dark with desire and fixed on her face as she'd moved above him.

"Rose Carter," he said, her name rolling off his tongue like a caress, like a secret shared in darkness. "Published at twenty-three. Youngest professor in the university's history. They call you The Glacier—beautiful, brilliant, and completely untouchable."

Heat crept up Rose's neck, spreading across her cheeks like a stain. "How do you—"

"I make it my business to know interesting people." His gaze traveled over her face with familiar intimacy, lingering on her lips in a way that made her breath catch. "Though I have to say, the rumors don't do you justice. They don't capture the way you look when you lose control."

The words hit her like a physical blow. Rose grabbed her briefcase with shaking hands, her pulse racing like she'd run a marathon. "Whatever you think last night was, you're mistaken. We are professor and student, nothing more."

"Are we?" Billy stepped aside as she moved toward the door, but his proximity made her skin prickle with unwanted awareness. The hallway beyond seemed impossibly far away, a distant promise of safety and sanity. "Because I remember someone who was very different from this ice queen act. I remember someone who begged me to—"

"That person doesn't exist." Rose's voice was sharp enough to cut glass, desperate enough to shatter it. "And if you think you can use what happened to manipulate me or my class, you're sorely mistaken."

She pushed past him into the hallway, her heels clicking against the polished floor with staccato urgency. The corridor buzzed with student activity—the ten-minute break between classes that filled Westfield University's academic buildings with controlled chaos. Conversations in multiple languages mixed with the sound of footsteps and slamming lockers, the normal soundtrack of academic life that now felt surreal and distant.

Billy's footsteps echoed behind her as she navigated toward the main staircase, his longer stride easily keeping pace with her hurried steps. The grand marble steps were one of the university's architectural prides, sweeping down three floors in elegant curves that had graced countless graduation photos and admissions brochures. Rose gripped the iron banister with white knuckles, her breathing shallow and rapid.

"Rose, wait."

The sound of her first name in that voice—intimate, knowing, dangerous—made her stumble slightly. She quickened her pace, but Billy's longer stride caught up easily, effortlessly.

"We need to talk about this like adults," he said, his voice lower now, meant only for her ears despite the crowds of students flowing around them.

"There's nothing to discuss." Rose didn't slow down, didn't look at him, couldn't risk seeing whatever expression he wore. "What happened was a mistake. It won't happen again."
