The invincible girl
The Invisible Girl
The city never really slept.
Even after midnight, Seoul still pulsed with life — car horns, streetlights, and laughter spilling out of bars that Haerin could never afford to walk into. From the window of the Kang family’s mansion, the skyline looked like a dream made of diamonds, each light glowing brighter than her entire world.
She pressed her forehead against the cool glass, clutching the cleaning rag in her hand. Her shift was supposed to end an hour ago, but one of the guests had spilled wine on the imported carpet, and the housekeeper had barked her name before she could even take a breath.
“Haerin, do it again. It still smells like alcohol.”
“Yes, ma’am.”
Her voice was soft, barely audible, and that was how she survived here — by being quiet.
In this house, silence was safety.
The Kang family mansion wasn’t just a home; it was a palace made of rules. Every corner gleamed with wealth — chandeliers dripping with crystal, marble floors cold enough to reflect your own reflection back at you like a reminder that you didn’t belong.
Haerin had worked here for almost a year now. She cleaned the rooms no one used, ironed suits for a man she’d never spoken to, and washed dishes from parties she wasn’t allowed to attend. The pay was good — good enough to keep her younger brother in school. That was all that mattered.
But sometimes, when she stood alone in the empty corridors, she wondered if anyone would ever remember she existed.

It was past 1 a.m. when she finally finished cleaning the living room. She stacked the last glass back onto the tray and exhaled quietly, her fingers aching. She looked at her reflection in the glass cabinet — tired eyes, hair falling out of her bun, a smudge of wine on her sleeve.
She smiled faintly. “Invincible,” she whispered to herself.
It was the word she used whenever she wanted to cry.

As she turned to leave, a faint sound caught her attention — something heavy hitting the floor upstairs.
Her first instinct was to ignore it. It wasn’t her business. Servants didn’t go upstairs unless summoned. But the sound came again — a muffled groan, a crash, then silence.
Haerin hesitated at the foot of the grand staircase.
Her heart pounded. What if someone was hurt?
Slowly, she climbed.
The upper floor was dark, only the hallway lights casting faint glows on the portraits of the Kang family — polished smiles, cold eyes. She reached the last door on the left, the one she had never been allowed near. Kang Minho’s room.
The heir.
Everyone whispered about him. Perfect grades, flawless reputation, soon-to-be CEO. The tabloids loved him, but the staff knew better — they said he barely spoke, barely slept. Some said he wasn’t cold; he was empty.
Haerin knocked once. “Sir?”
No answer.
She knocked again. “Sir, are you okay?”
Still nothing.
Her fingers trembled as she turned the handle. The door was unlocked.
The smell hit her first — alcohol and something else… metallic.
Her eyes widened.
Minho was on the floor beside his desk, his white shirt stained red near his wrist. A shattered glass lay next to him. His face was pale, his breaths shallow.
“Oh my God—” Haerin dropped to her knees, instinct overtaking fear.
She pressed the cloth she was holding against his wrist, shaking. “Sir, stay with me. Please.”
His eyes fluttered open — unfocused, glassy, then locking onto hers.
For a second, time stopped.
No one ever looked at her like that — not like she was background noise, not like she was invisible.
His lips parted, voice barely a whisper. “Who… are you?”
“Haerin,” she said, tears stinging her eyes. “Just—just stay awake.”
He gave a faint, bitter smile. “Figures… even the maid cares more than my fiancée.”
Her chest tightened. She didn’t understand what he’d done or why, but in that moment, she didn’t care. She wrapped her scarf around his wrist, pressed it tight, and called for help.
The next few minutes blurred — shouting, the butler rushing in, the doctor summoned in secret so the media wouldn’t find out.
Haerin stepped back into the corner, shaking as they carried him out. No one looked at her. No one asked who had found him. It was as if she didn’t exist again.
And yet, when they wheeled him past her, Minho’s eyes opened one more time.
They met hers.
He didn’t say a word, but that look…
It was enough to change everything.

Later, when the mansion fell silent again, Haerin sat alone in the servants’ quarters, unable to sleep. Her hands still smelled faintly of blood and whiskey.
Maybe she shouldn’t have gone upstairs. Maybe she should’ve pretended she didn’t hear anything. That would’ve been safer. That would’ve been normal.
But something deep inside her whispered that tonight was only the beginning.
Because for the first time in her life, someone who was never supposed to see her… did.
And the man she shouldn’t love had finally noticed the girl he was never meant to meet.
