The hostel stood at the edge of campus like a quiet observer of youth—five floors of pale concrete and long corridors that carried laughter during the day and whispers at night. Behind it ran a small riverside, narrow but steady, its water glinting beneath streetlamps like liquid silver. Students often gathered near the banks in the evenings, but very few ever looked up at the fifth floor terrace.
That space belonged to them.
Room 511 was at the end of the corridor on the top floor. It had two single beds pushed slightly apart, mismatched study lamps, a wide window overlooking the river, and walls that slowly became a reflection of the two girls who lived there.
On one side: posters of glossy sport cars—Ferraris, McLarens, Lamborghinis—lined with neat precision. The desk beneath them was rarely tidy. Car magazines stacked in corners, keys of borrowed bikes, scribbled notes about future dreams.
That was Eunbi’s side.
On the other side: sketches taped carefully to the wall—characters mid-motion, storyboards in pencil, frames of imaginary worlds. Animation books, drawing tablets, neatly arranged color swatches.
That was Hyejin’s.
They had been roommates for two years now, and somewhere between shared midnight snacks and exam stress breakdowns, something deeper had grown—something neither of them had named at first.
Eunbi was loud, emotional, passionate about everything she loved. If she admired something, she admired it openly. If she loved someone, she loved them with her entire heart. She was openly possessive, quick to wrap an arm around Hyejin’s waist when someone leaned too close, quick to glare when someone laughed a little too long at Hyejin’s jokes.
Hyejin, on the other hand, was calm.
Almost dangerously calm.
She didn’t need to glare. She only needed to look. There was a quiet intensity in her eyes that made people step back without knowing why. She rarely raised her voice, but if someone dared cross a line with what she considered hers, she would dismantle them with a precision so controlled it felt surgical.
And Eunbi was hers.
The hostel’s fifth floor had a maintenance terrace door at the end of the hallway, technically locked, but the latch had been faulty for months. Most students didn’t notice. Eunbi did.
One late evening in their second semester, she had pushed it open out of curiosity and found a small, open cement space overlooking the river. The view was unobstructed. The city lights shimmered beyond the trees. The sound of water below was constant and soothing.
She had grabbed Hyejin’s wrist and dragged her up there.
“Look,” Eunbi had whispered dramatically, spreading her arms as if presenting a grand kingdom. “Our secret place.”
Hyejin had stepped forward quietly, wind brushing her dark hair back from her face.
“It’s peaceful,” she said.
And from that day on, it became theirs.
They would sit there after curfew, sharing stories, leaning shoulder to shoulder. Sometimes Eunbi would lie flat on the cool cement and talk about the sport car she would buy one day.
“Red,” she would say confidently. “Bright red. I’ll drive it along the river road. You’ll sit in the passenger seat.”
Hyejin would glance down at her. “Why passenger?”
“Because I’m driving.”
Hyejin would smirk faintly. “We’ll see.”
Eunbi loved that about her—the quiet challenge in her tone.
But beneath Eunbi’s boldness was something softer. She was deeply emotional when it came to the people she loved. If Hyejin had a bad critique in her animation class, Eunbi would skip her own club practice just to sit with her. If someone made a careless comment about Hyejin’s work, Eunbi would hold onto the irritation for hours.
One afternoon, during a campus festival, a senior from Hyejin’s department grew a little too friendly. Laughing too close. Touching Hyejin’s shoulder casually.
Eunbi saw it from across the lawn.
Her jaw tightened.
Later that evening in Room 511, she paced near the window.
“She was leaning on you,” Eunbi said.
Hyejin sat calmly at her desk, sketching. “She was showing me her project.”
“She didn’t need to lean.”
Hyejin’s pencil paused.
She stood, walked slowly toward Eunbi, and stopped just inches away.
“Are you jealous?” she asked softly.
Eunbi crossed her arms. “No.”
“Liar.”
Eunbi’s cheeks flushed.
“I just don’t like people thinking they have a chance.”
Hyejin reached up and tucked a strand of hair behind Eunbi’s ear.
“They don’t.”
The simplicity of that statement made Eunbi’s heart race.
That night, they went up to their terrace.
The sky was deep navy, scattered with faint stars. The river below reflected city lights in broken streaks. The wind was cooler than usual, brushing against exposed skin.
They sat close.
Closer than normal.
Eunbi didn’t know when her fingers started moving. Maybe it was the quiet. Maybe it was the way Hyejin tilted her head while watching the water.
Eunbi reached out, brushing her fingertips lightly along the side of Hyejin’s neck.
Hyejin stilled.
“What are you doing?” she asked, voice low but steady.
Eunbi swallowed. “Nothing.”
Her fingers traced upward again, slower this time. The skin there was warm. Sensitive. Hyejin’s breathing shifted almost imperceptibly.
Eunbi moved closer, playful but trembling underneath.
“You react so easily,” she whispered teasingly.
Hyejin turned her head slightly, exposing more of her neck without meaning to.
Eunbi’s heart pounded.
Her thumb brushed beneath Hyejin’s ear, lingering.
“Hyejin,” she murmured, barely audible.
“Yes?”
The calm in Hyejin’s voice made Eunbi bolder.
Without fully planning it, she leaned forward and pressed her lips softly against Hyejin’s.
It was gentle. Hesitant. A question wrapped in warmth.
For a brief second, Hyejin didn’t move.
Then her hand slid to Eunbi’s waist, firm and grounding.
When she kissed back, it wasn’t hesitant.
It was slow, controlled, claiming.
Eunbi melted into it instantly.
When they pulled apart, their foreheads rested together.
“You kissed me first,” Hyejin said quietly.
Eunbi nodded, breath uneven. “Yeah.”
Hyejin’s fingers tightened slightly at her waist.
“Good,” she replied. “I was waiting.”
After that night, their dynamic shifted in subtle but undeniable ways.
Hyejin became even more protective. She didn’t need to speak much. A single arm around Eunbi’s shoulders when someone got too close was enough. Once, when a classmate tried flirting with Eunbi in the hallway, Hyejin simply stepped between them and smiled politely.
“She’s busy,” Hyejin said.
The classmate backed away instantly.
Eunbi, for all her loud possessiveness, felt something entirely different under Hyejin’s quiet dominance. It wasn’t overwhelming—it was grounding. Hyejin’s hands at her waist, guiding her closer. Hyejin’s calm voice telling her to sit still when she got restless.
Inside Room 511, their evenings grew softer.
Eunbi would lay across Hyejin’s lap while she animated, playing absently with the hem of her shirt. Sometimes Eunbi would trail her fingers along Hyejin’s neck again, knowing exactly how it made her inhale sharply.
“You like doing that,” Hyejin would murmur.
“You like when I do.”
Hyejin would tilt her head slightly, exposing her neck again in silent agreement.
The winter came quietly.
One evening, snow dusted the terrace floor in white. They stood facing the river, breath visible in the cold air.
Eunbi stepped behind Hyejin, wrapping her arms around her waist.
“Mine,” Eunbi whispered playfully.
Hyejin turned within her hold, cupping Eunbi’s face.
“Careful,” Hyejin murmured, eyes dark and steady. “I’m far more possessive than you.”
Eunbi’s pulse quickened.
“I know.”
Hyejin leaned down and kissed her slowly, deliberately, as snowflakes melted in their hair.
Room 511 became more than just a shared dorm. It became a space of quiet confessions and steady intimacy. Of hands finding each other in the dark. Of whispered promises about the future.
Eunbi would talk about buying her dream car and driving along the river road.
Hyejin would talk about animating a story inspired by a five-floor hostel and a reckless girl who loved too loudly.
“Who’s reckless?” Eunbi would protest.
“You,” Hyejin would reply calmly.
But there was softness behind her eyes.
Years later, they might leave the hostel. They might leave the river behind.
But Room 511 would always be where Eunbi first dared to brush her fingers along Hyejin’s neck.
Where she leaned in first.
Where calm met fire.
Where possessiveness softened into devotion.
And where love, quiet and fierce all at once, found its home on the fifth floor above a small, shining river.
