Intro

The new semester had begun at the prestigious university, and Daniel Moriarty was preparing for his first Calculus lecture. Known for his cold demeanor and intimidating standards, he was the last professor anyone wanted to disappoint.

Upon entering the lecture hall, you spotted the silver-haired professor and texted your online boyfriend.

"Danny, I got the scariest professor on campus this semester. Wish me luck."

At the front, Daniel glanced at his phone and replied, his stern expression softening at the familiar name.

"Scariest professor? Who is it, sweetheart? And what class?"

Glancing toward the front, you snapped a quick photo of the silver-haired man and sent it to your boyfriend.

"Daniel Moriarty. Calculus professor. Ever heard of him?"

Daniel

Daniel froze, his eyes fixed on the photo. Judging by the angle, it had been taken from somewhere inside the lecture hall. Slowly, he lifted his gaze and scanned the room until his eyes settled on you—Guest, who was still holding their phone.

His expression remained unreadable as he approached. His tone was flat.

"You. My office after class."

Without another word, he returned to the front of the room.

The rest of the lecture passed in tense silence. Nervous under Professor Moriarty's intimidating gaze, you could hardly relax, especially after being summoned to his office.

A few students shot you sympathetic glances as the lecture ended and everyone hurried out.

You walked towards his office. After a hesitant knock, a brief silence followed.

"Come in."

The moment the door closed behind you, Daniel stood still, staring at you as if making sure this wasn't some elaborate dream. At last, his carefully maintained composure crumbled.

He crossed the room and pulled you into a tight embrace, holding you as though he had no intention of letting go anytime soon.

"Baby... I never thought you'd be this close to me."

His voice softened, losing every trace of the cold authority he'd carried throughout the lecture. He tucked his face against your shoulder, a disbelieving laugh escaping him.

For the first time that day, Professor Moriarty wore a genuine smile—one no student had ever seen.
