Edward paced at the front of the lecture hall, his voice filling the room as he explained the intricacies of chemical theory to a sea of students. The late afternoon sunlight filtered through the high windows, casting a warm glow on the wooden desks and polished floors. He was in his element here, his sharp mind and even sharper tongue keeping the class engaged - or at least intimidated enough to pay attention.

But his rhythm faltered the moment his gaze drifted toward the back of the room.

Sitting near the door, legs crossed and an air of nonchalance about him, was Roy Mustang. He wasn't scribbling notes like the students around him; instead, he was watching Edward with an expression of amused interest, a faint smirk playing on his lips.

Edward nearly dropped his chalk.

"...and, uh, as I was saying," he stammered, quickly turning back to the board. He could feel the heat creeping up his neck. What was Roy doing here?

He forced himself to refocus, finishing the lecture without further incident. But as the students filed out of the hall, Ed's eyes flicked back to Roy, who remained seated, clearly waiting for him.

Ed sighed, bracing himself as he packed up his notes. When he finally approached, he crossed his arms and glared down at the seated man.

"What are you doing here? This isn't a public event."

Roy's smirk widened. "I'm expanding my horizons. Isn't that what Harvard's all about?"

Edward rolled his eyes. "You don't need a lecture on chemistry for whatever shady business endeavors you're into."

Roy leaned back, unbothered by the jab. "Maybe not, but I do appreciate a good lecture. And you're an excellent speaker, Professor Elric."

Ed didn't know what to say. He opened his mouth to retort, but before he could, a familiar voice interrupted.

"Edward, excellent work today, as always."

Professor Sheffield, a distinguished older man with silver hair and an air of quiet authority about him, approached the pair. His eyes widened as he noticed Ed's guest.

"Roy Mustang," Sheffield said warmly, extending a hand. "It's been years! What a pleasant surprise to see you here."

"Professor Sheffield," Roy replied, standing and shaking the man's hand. His tone was polite, even friendly, but there was a certain ease to his posture that suggested this wasn't their first meeting.

"You know him?" Edward asked, his confusion evident.

Sheffield chuckled. "Of course. Roy was one of my brightest students back in the day. Top marks in strategic theory and economics, if I recall correctly. Though he had a knack for skipping my lectures and charming his way through finals."

Edward blinked, his mind racing to reconcile this new information. "You went to Harvard?"

Roy's smirk returned, though it was softer. "Guilty as charged."

Ed's eyes narrowed. "You never mentioned that."

"You never asked," Roy said with a shrug.

Sheffield clapped Roy on the shoulder. "We'll have to catch up sometime. You'll have to join us at the faculty fundraiser next week."

"I'd be honored," Roy said smoothly, but his gaze remained fixated on Edward, who was still staring at him.

Sheffield excused himself, leaving the two of them alone again. Edward finally found his voice. "You're unbelievable, you know that?"

"What can I say?" Roy replied, slipping his hands into his pockets. "I'm full of surprises."

Ed shook his head, his frustration tempered with curiosity. "Why are you really here, Mustang?"

Roy hesitated, his smirk fading into something more genuine. "I was curious about you. After our last meeting, I couldn't stop thinking about how someone so young managed to carve out such a place for himself here. I wanted to see you in your element."

The young professor stared at him, caught off guard by the admission. "You…came here just to hear me lecture?"

"That, and to make sure I hadn't scared you off," Roy teased lightly, though there was a hint of sincerity in his tone.

Ed snorted, crossing his arms. "It takes more than spilled coffee to get rid of me."

"I'm counting on it," Roy said, his voice softening.

The way he said it - low and earnest - made Ed's breath hitch for a moment. He quickly looked away, gathering his bag and papers. "Well, if you're so interested in learning, you can read my book when it's published. Now, if you'll excuse me, I have actual work to do."

Roy stepped aside, watching as Edward strode toward the door. But just as he reached it, Roy called out, "Professor."

Ed paused, glancing back over his shoulder.

"Dinner," Roy said, his tone casual. "Tomorrow night. My treat."

Ed's brow furrowed. "Why?"

The businessman shrugged. "Consider it a continuation of your lecture. I have a lot of questions, and I'd rather not wait for the book."

Ed rolled his eyes but couldn't hide the faint smile tugging at his lips. "Fine, but don't expect me to go easy on you."

Roy's grin widened. "Wouldn't dream of it."

As Ed left the lecture hall, he couldn't help but feel as if he'd just agreed to more than a simple dinner. And for reasons he couldn't quite explain, the thought didn't bother him as much as he thought it should.

—

The restaurant Roy chose was upscale but not ostentatious, tucked away on a quiet cobblestone street off Harvard Square. The kind of place with candlelit tables and a piano, where jazz standards drifted through the air like a lullaby.

Edward arrived a few minutes late, still unsure as to why he had agreed to this. His usual attire, a simple shirt and tie, felt underdressed compared to the polished clientele, but he refused to care. It was Roy's idea, after all. If the man had an issue with it, too bad.

Roy was already seated, a wine glass in hand, looking at ease in a gray suit. His tie was loosened just enough to hint at a relaxed demeanor. He stood as Edward approached, pulling out the chair across from him.

"You made it," Roy said with a small smile, his voice warm but teasing.

"I said I would," Edward replied, sitting down and eyeing him. "You're lucky I'm curious enough to put up with this."

Roy chuckled, gesturing for the waiter. "Curiosity is a good start. Care for a drink?"

"Just water," Edward replied, brushing off the wine menu Roy offered.

"Suit yourself," Roy said, a flicker of amusement in his eyes as he signaled for the waiter once more.

The initial pleasantries were straightforward enough. Edward wasn't one for small talk though, and Roy seemed content to let the silences stretch, studying Ed as if he were the only thing worth noting in the room. It wasn't until their meals arrived that Edward finally broke the tension.

"So," Edward began, his fork paused mid-air. "Why Harvard? You don't strike me as the academic type."

Roy leaned back in his chair, his wine glass swirling in his hand. "Let's just say I had ambitions beyond my circumstances. Harvard was a means to an end."

The younger man raised an eyebrow. "What kind of circumstances?"

Roy's smile thinned, his gaze dropping to the crimson liquid in his glass.

"Nothing as dramatic as a chemist's journey, I'm sure. I grew up in a small industrial town, a place where the only futures were working the mills or escaping them. I chose the latter."

Ed frowned, surprised by the honesty. He'd expected charm and evasions, not this. "And Harvard was your way out?"

"It opened doors," Roy admitted, meeting his gaze again. "But it was the people I met there who taught me the most. People like Sheffield. People like you."

Edward blinked, caught off guard. "You've barely met me."

"And yet, you're already proving my point," Roy said with a faint smile. "You don't realize it, but you're fascinating, Edward. You've achieved more at your age than most people do in a lifetime, and yet you don't carry the arrogance of someone who's always known success. That's rare."

Ed scoffed, though his cheeks flushed. "You're giving me too much credit. I've had my share of failures."

"Failure is just another kind of lesson," Roy said quietly. "The important part is what you do with it.

Ed fell silent, his fork forgotten as he studied his companion. Beneath the smooth exterior and quick wit, there was something deeper, something harder to define. And for the first time, Ed wondered if Roy's charm wasn't just a mask but also a shield.

"What about you?" Edward asked, leaning forward. "What's your big plan, Mustang? You don't seem like the type to sit back and let life happen to you."

Roy's grin returned, though it lacked its usual sharpness. "I've been asking myself that a lot lately. When I was younger, it was all about climbing the ladder, proving to the world - and myself - that I belonged. But now…" He trailed off, his gaze drifting.

"Now what?" Ed pressed.

Roy looked back at him, his expression soft and open in a way that made Edward's pulse quicken. "Now I think it's about finding something worth fighting for. Someone, maybe."

Edward swallowed, suddenly hyper-aware of the warmth of the room, the low murmur of conversation, the way Roy's eyes seemed to linger on him a fraction too long.

"Don't tell me you're trying to recruit me for some grand cause," Edward said, his tone half-joking in an attempt to deflect.

Roy chuckled, shaking his head. "Not tonight. Tonight, I'm just a man having dinner with a very interesting professor."

Edward didn't know what to say to that. He stabbed at his food, hoping to distract himself, but his appetite had faded.

The rest of the evening passed in a blur of conversation - less guarded now, more fluid. Edward found himself talking about his research, his frustrations with the academic world, even his brother, Alphonse, who had stayed back in Germany to pursue his own studies. Roy listened intently, asking the kind of questions that made Ed realize he hadn't had a conversation like this in a long time.

By the time they left the restaurant, the chill of the night air was a welcome contrast to the warmth that lingered between them.

"Let me walk you back," Roy offered, his hands tucked into his pockets.

Ed hesitated but eventually nodded. "Fine, but don't think this means you're off the hook for spilling coffee on me."

Roy laughed, bright and genuine, falling into step beside him. "I'd never assume."

The walk was quiet, the streets nearly empty save for the occasional car or passerby. When they reached Edward's building, they paused at the steps, the faint glow of a streetlamp casting long shadows around them.

"Well," Edward said, looking around, adjusting his bag. "Thanks for dinner."

Roy tilted his head, studying him with an unreadable expression. "My pleasure. And Edward?"

"Yeah?"

Roy stepped closer, just enough to invade Edward's space without overwhelming it. Ed could smell his cologne, spicy and intoxicating. Roy's voice was low, almost hesitant. "I meant what I said earlier. You're fascinating. Don't let anyone convince you otherwise."

Edward's breath caught, his pulse racing. For a moment, he thought Roy might —

But Roy stepped back, his smile soft and knowing. "Goodnight, Professor."

Edward watched him walk away, a strange mix of frustration and warmth swirling his chest. He didn't know what to make of Roy Mustang, but one thing was certain: he wasn't getting him out of his head anytime soon.
