The library exhaled its last breath of daylight.
Shadows stretched like sleepy cats across the floor, swallowing the golden warmth inch by inch. Students trickled out in clusters, laughter fading into the corridor until only the quiet hum of evening remained.
Eun-ji didn't move.
Neither did Ji-ho.
It was that strange, suspended moment… where time felt like it was holding its breath just for them.
"You're still here," she said, tapping her pen lightly against the table.
"So are you," he replied, closing his notebook with a soft, deliberate snap.
Touché.
A silence settled, softer now, less teasing, more… aware.
Eun-ji tilted her head, studying him like a puzzle she refused to give up on. "You know," she began, voice quieter than before, "most people leave before it gets dark."
Ji-ho's gaze flicked toward the tall windows. The sky had deepened into a dusky violet, the kind that made secrets feel braver.
"I'm not most people," he said.
There it is again.
That line. That distance.
Eun-ji leaned forward, resting her chin on her hand. "No," she murmured, eyes glinting, "you're definitely not."
A beat.
Then she stood.
"Come on."
Ji-ho blinked. "Where?"
She slung her bag over her shoulder, already walking backward toward the exit, a mischievous spark dancing in her eyes. "You said you don't relax here, remember? So show me."
"That's a bad idea," he said instantly, rising anyway.
"Good," she shot back. "I'm in the mood for one."

Outside, the air was cooler, brushed with the faint scent of night-blooming flowers. The campus had transformed. What was bright and ordinary hours ago now felt like a stage set for something quieter… and far more dangerous.
Eun-ji walked ahead, then turned, walking backward again, facing him.
"Alright, pumpkin," she said, pointing at him. "Rule number one. No mysterious silence."
He slipped his hands into his pockets. "That's not a rule I can follow."
"Then break it," she challenged.
His lips twitched.
They passed beneath a row of dim streetlights. One flickered as they walked under it.
Ji-ho's steps slowed.
Eun-ji noticed immediately. Of course she did.
"You don't like the dark either?" she teased lightly. "Or is it just sunlight that's your enemy?"
He stopped.
Completely.
The air shifted.
Eun-ji took one more step before realizing he wasn't beside her anymore. She turned.
Ji-ho stood a few feet back, half-shadowed, the faint glow of the streetlight catching only part of his face. His expression… wasn't playful anymore.
It was careful.
Measured.
"Cherry," he said quietly, "go back."
Her brows knit together. "What?"
"Go back to the dorm."
She laughed once, short and disbelieving. "You dragged me out here and now you're sending me back? That's rude."
"I didn't drag you," he replied, voice low. "You followed."
"Same difference."
"No," he said, sharper this time. "It's not."
That made her pause.
Something was… off.
Not the usual off. Not the teasing, mysterious, annoyingly intriguing kind.
This was different.
Then she heard it.
Footsteps.
Not theirs.
Slow. Uneven. Approaching from the darker path behind Ji-ho.
Eun-ji's eyes flicked past him. "We're not alone."
"I know," he said.
Of course he does.
Her pulse quickened, but not from fear. From anticipation. From that same thrill that had been tugging at her since the beginning.
"Friend of yours?" she asked.
Ji-ho didn't answer.
The figure stepped into the faint light.
A boy. Maybe their age. But something about him felt… wrong. His posture was stiff, his movements slightly delayed, like a puppet catching up to its strings.
And his eyes—
Locked onto Ji-ho.
Hungry.
Eun-ji's smile faded just a little. "Okay… that's new."
Ji-ho took a step forward, subtly placing himself between her and the stranger.
"Leave," he said, voice no longer soft, no longer teasing.
The boy tilted his head.
"You smell different," he muttered.
Eun-ji blinked. "Excuse me?"
Ji-ho's shoulders tensed. "Don't engage."
Too late.
Eun-ji stepped to the side, peeking around him. "You know, that's a very weird way to start a conversation."
The boy's gaze snapped to her.
For a second… something flickered in his expression.
Recognition?
No.
Interest.
A slow, unsettling smile stretched across his face.
"Ah," he whispered. "That's why."
Ji-ho moved instantly.
One second he was beside her—
The next, he had her wrist, pulling her behind him, grip firm but not hurting.
"Don't look at him," he said under his breath.
Her heart slammed against her ribs.
Not from fear.
From realization.
Oh.
Oh.
Every strange detail. Every flinch. Every warning.
Every hint.
Eun-ji's lips parted slightly, her voice barely above a whisper.
"Ji-ho…"
The streetlight above them flickered again.
And for just a split second—
His eyes caught the light.
Not dark brown.
Not human.
Something deeper.
Something that didn't belong to the daylight world.
Her breath hitched.
"…you're not kidding anymore, are you?"
He didn't answer.
Didn't need to.
Because the boy in front of them took another step forward, grin sharpening—
—and Ji-ho's grip on her tightened, his voice dropping into something ancient, dangerous, and very real:
"Run."
