Your neighbor, Lee Minho, was the kind of man people rarely noticed.

Cold. Polite. Distant.

He existed in the margins of everyday life—quiet nods in the hallway, brief murmured greetings near the elevator, eyes that never lingered long enough to invite conversation. To anyone else, he was just another face in the building. Forgettable. Harmless.

If only that were true.

Minho had perfected the art of restraint. His life ran on discipline and silence, every day following the same careful pattern. He had learned young that emotions were liabilities—unpredictable, corrosive things that ruined people who let them fester. So he buried his beneath routine and control, wore indifference like armor, and made sure no one ever looked twice.

Especially you.

By day, he passed you with practiced neutrality. By night, the thin walls of civility dissolved.

You slept unaware in your apartment, cocooned in safety you didn’t know was fragile. Minho didn’t need cameras or recordings—he studied you through repetition. Through timing. Through the way your footsteps echoed at the same hour every evening, the rhythm of your lights turning on one by one, the soft glow behind your curtains before bedtime.

Patterns were honest. People were not.

From the darkness of his own living room, Minho sat perfectly still, gaze fixed on the faint illumination across the way. He didn’t need to see you clearly anymore. His mind supplied every detail with unnerving precision—the curve of your shoulders, the way you moved through your space without fear, the softness you carried without knowing how exposed it made you.

You were careful. Kind. Unaware.

And that vulnerability awakened something in him he had spent years suppressing.

His jaw tightened, fingers curling slowly as a thought settled into place—not impulsive, not emotional, but terrifyingly composed.

She’s going to be mine.

Not a wish. Not a fantasy.

A conclusion.

Only mine.

When the light in your apartment finally went out, Minho leaned back, shadows swallowing his expression. His breathing remained steady, controlled. Another night without action. Another boundary left intact.

For now.

Because Minho wasn’t reckless.

He was patient.

And whatever darkness he carried, whatever secret obsession had taken root so quietly, he intended to protect it—nurture it—until the day you stepped into his world willingly…

never realizing how long he’d been standing just beyond the edge of yours, watching from the dark.
