The sound of the key sliding into the lock hit like a gunshot in slow motion. Ji-Yeon froze on top of Sung-Min. Her breathing cut off mid-breath. Eyes wide, locked on the bedroom door that wasn't even fully closed. Just ajar. Enough for the living-room light to spill in.
Sung-Min felt her heart hammering against his chest like it wanted to break free.
No time for clothes. No time to crawl under the bed like in some cheap comedy. Only time for one decision.
He moved fast. Rolled with Ji-Yeon to the side, covered her with his own body, and yanked the crumpled sheet up to their waists. It wasn't much, but at least they weren't completely exposed.
Tae-Ho's footsteps echoed in the living room. Heavy. Slow. Like he was searching for something.
"Ji-Yeon?" His voice came out rough, laced with alcohol and something darker underneath. "You here?"
She swallowed hard.
Sung-Min squeezed her hand under the sheet. A short signal: stay quiet.
Tae-Ho stopped at the bedroom threshold. The hallway light lit half his face. Sweat on his forehead. Gym T-shirt clinging to his chest. Eyes bloodshot. Not fully drunk. Just enough for the rage to come out unfiltered.
He looked at the bed. Saw the two shapes under the sheet. Saw Ji-Yeon's hair spilling out. Saw Sung-Min's hand resting protectively on top of the fabric.
And he froze.
A silence that stretched forever.
Then Tae-Ho let out a laugh. Low. Bitter. Humorless.
"I knew you were a whore," he said slowly. "But I didn't think you were stupid enough to bring him here."
Ji-Yeon trembled. She tried to speak, but only a choked sound came out.
Sung-Min sat up a little, still holding the sheet. His voice came out calm. Too calm.
"It's not what you think."
Tae-Ho took one step into the bedroom.
"No?" He pointed at the clothes scattered on the floor. His T-shirt. Her jeans. The torn red bra still dangling from the back of the chair. "Then what is it? You two studying together?"
Sung-Min didn't answer.
Tae-Ho took another step.
"Get up, asshole. I want to see your face when I break your jaw."
Ji-Yeon clutched Sung-Min's arm.
"No… Tae-Ho, please…"
"Shut up," he snapped without looking at her. "This isn't about you anymore."
Sung-Min moved slowly. He sat on the edge of the bed, the sheet wrapped around his waist like an improvised toga. He met Tae-Ho's eyes directly.
"I'm not going to fight you," he said. "Not here. Not with her watching."
Tae-Ho let out another laugh. This one sounded more broken.
"Now you care? Now you pretend you've got honor?"
"I'm not pretending anything," Sung-Min stood up. The sheet slipped a little, but he didn't let it fall. "I'm just saying if you want to settle this, we settle it outside. Like men. Without dragging her into it."
Tae-Ho looked him up and down. Naked except for the sheet, hair messed up, scratch marks on his shoulders. And still, Sung-Min didn't drop his gaze.
Something shifted in Tae-Ho's stance. Not fear. Confusion. Like he'd expected Sung-Min to run or beg. And instead, there he was. Standing. Calm. Almost defiant.
Tae-Ho clenched his fists until the knuckles turned white.
"Get out," he said finally. "Now."
Sung-Min nodded once. He bent down, picked up his clothes from the floor with precise movements. Boxers and jeans first, no rush. Then the T-shirt.
Ji-Yeon stayed sitting on the bed, sheet clutched to her chest, staring at the floor like she wanted to vanish.
When Sung-Min was dressed, he stepped close to her for a second.
"Call me when you want," he murmured. Just for her to hear.
Ji-Yeon didn't look up. She only nodded once, very slightly.
Sung-Min walked past Tae-Ho without brushing him. The other man stepped aside just enough to let him through. He smelled like beer and old sweat.
In the living room, Sung-Min paused at the front door. He looked back.
Tae-Ho still stood in the bedroom doorway, staring at Ji-Yeon like he didn't know what to do with her anymore.
Sung-Min opened the door. Stepped out.
The hallway felt cold.
He walked down the stairs slowly.
When he reached his own apartment, he locked the door behind him. Pressed his forehead against the wood for a moment.
His phone buzzed in his pocket.
He pulled it out.
System[Critical event detected. Direct confrontation avoided. Ji-Yeon: critical emotional state. Tae-Ho: hostility level 94%.][Reward for restraint: +6 Cold Blood. Stats updated.][Warning: Relationship with Park Ji-Yeon has entered imminent breakup phase. Possible secondary consequences within the next 48 hours.]
Sung-Min let the phone drop onto the couch. He sat down. Ran both hands over his face.
And for the first time in weeks, he didn't smile.
Not because he was afraid.
But because, for one very brief moment, he felt something close to pity.
Not for Ji-Yeon.
But for the man he'd just left in that room, staring at his girlfriend like he no longer knew who she was.
The castle hadn't completely collapsed yet.
But the first important card had fallen.
And the sound it made hitting the floor was much louder than he'd expected.
