My Roommate is an Ancient Demon

LIVING WITH A DEMON

“BZZZT! BZZZT! BZZZT!”

The buzzing sound of the alarm clock pierced sharply through the quiet of the room, jolting Andrea awake in an instant. She lifted her head with a small, pained groan, her cheek stiff and sore from resting against the hard wooden surface of her study table all night. Her glasses were sliding crookedly down her nose, her hair was a tangled mess, and her mind felt thick and foggy, as if she had only just closed her eyes a few minutes ago.

Blinking rapidly to clear her blurry vision, she fumbled one hand across the table, knocking over a pencil and brushing against the edge of an open notebook before her fingers finally closed around the small alarm clock. With a heavy sigh, she pressed down firmly on the button, and the buzzing noise fell silent.

Peace returned to the room, broken only by the soft, steady tap tap tap of rainwater still dripping from the gutter outside and tapping lightly against the windowpanes. The violent thunderstorm from the night before had long passed, leaving behind a cool, damp breeze that drifted through the slightly open window, carrying the fresh scent of wet concrete and greenery.

Right I fell asleep while reviewing my notes, she thought to herself. Andrea rubbed the back of her stiff neck and stretched her arms high above her head, letting out a long yawn. For a moment, everything felt ordinary . Just another late night cramming for exams, just another groggy morning before class. Faint images drifted through her mind, the book from the shelf, the thunder, a white-haired demon...

"What a strange dream,” she muttered to herself, shaking her head as if trying to chase the images away.

She pushed herself fully upright and turned to look at the floor, half‑expecting to see the faint lines of the symbol still smudged there. But the wooden planks were clean, smooth, and empty. No chalk dust, no marks, nothing out of place. She glanced toward the bookshelf too. The same large book she had knocked over was sitting neatly back in its spot, blending in perfectly with the rest, as if it had never moved at all.

Feeling a little more settled, she reached up to fix her glasses and turned toward the other side of the room, ready to start her usual morning routine. But the words died in her throat, and every muscle in her body froze on the spot.

Her heart skipped a beat, then began hammering wildly against her ribs, loud enough that she was sure she could hear it echoing in her own ears.

There, lying sprawled across her bed, was exactly the figure from her so‑called “dream.”

He was stretched out comfortably on his back, one strong arm tucked lazily behind his head, the other resting loosely over his stomach. His white hair fell in messy strands across the pillow, framing a face that looked deceptively young yet carried an air of an unshakable calm. His dark jacket was draped casually over the edge of the mattress, and his breathing was slow, deep, and steady, completely at ease in a room that was not his.

“Ow!” she stood frozen for a moment. So this is not a dream.

Slowly, as if sensing her panic, the man on the bed stirred. His long lashes fluttered open, revealing those same striking golden‑amber eyes, bright and alert even after hours of rest. He turned his head lazily toward her, a faint, unimpressed smirk tugging at the corner of his lips, as if he had been waiting for her to notice him all along.

“Humans of this era really take long enough to wake up,” Kael said in that same deep, calm voice she remembered , smooth, low, and carrying a weight that felt far older than his appearance suggested.

Andrea stood there, her mind scrambling to process what she was seeing. The relief she had felt just seconds ago vanished completely, replaced by a mix of shock, and confusion.

“You… you’re actually here,” she whispered.

Kael pushed himself up into a sitting position, running a hand through his messy white hair to brush it back from his face. His horns peeked through more clearly now, small but unmistakable, and his amber eyes scanned her from head to toe. Taking in her disheveled hair, her oversized pajamas, and the bewildered expression on her face.

Andrea took a small step back, her hand instinctively reaching behind her until her fingers touched the edge of the study table, as if it could offer her some kind of protection. “But it was a mistake! I simply wanted to try a simple spell, a focusing spell but I accidentally drew another line because the lightning startled me. I definitely didn’t want to summon anyone, let alone a demon!”

“Yet here we are,” Kael said, standing up to his full height. He was taller than she remembered, and even without trying, his presence filled the room, making the air feel heavier and cooler than it had been just moments before. “You made the mistake, you paid the price, and now we are both stuck with the consequences. Though I must say, being bound to a student who can barely draw a simple spell without messing it up is not exactly how I imagined spending my time either.”

"Wowwww." she said in disbelief. This demon really thinks he's some kind of a star. "Look at you, acting like some kind of a hot leading man."

"You think I'm hot?" he asked.

Her cheeks grew warm, she knew she was blushing. "What? No!" she grabbed a pen and threw it at him, which he caught easily with one hand. She walked out toward the kitchen while her cheeks were still red.

She prepared two bowls of corn flakes drowning in milk and two cups of coffee. She had no idea what a demon would eat, but surely no one could resist a good cup of coffee she thought.

"Kael!" she shouted out from the kitchen hoping he could hear her. "Come here, the food-"

Before she could even finish her sentence, black smoke came out of nowhere and suddenly Kael was sitting on the chair facing her.

She sighed. "Maybe I should just get used to you appearing out of smoke" she said. She slided the bowl of cornflakes and the cup of coffee toward him.

"You must be hungry." she said, hoping he would like it.

"An offering." he replied. "I'll accept it."

"What? No! It's not an offering!"

He grinned, then put his palms together and closed his eyes then the cereals and coffee began to glow, shining like stars and polished diamonds in the most beautiful light she had ever seen. Then the food disappeared completely.

"What was that?" she asked, wide-eyed.

Their eyes met and she noticed his amber eyes were glowing faintly. But before she could think too much about it, he leaned back to his chair looking satisfied.
