Genre: Thriller | Mystery | Psychological

Setting: Modern-day Seoul, Korea

Main Characters:

Kim Yeon (김연) – A quiet, observant man in his early 30s. A criminal psychologist with a mysterious past. Reserved but deeply empathetic.

Seo Mirae (서미래) – The female lead. A freelance journalist investigating missing women in Seoul. Smart, bold, and emotionally scarred from a past relationship.

Jang Haemin (장해민) – The villain. A charming, obsessive ex-boyfriend of Mirae. On the surface, he's a successful entrepreneur; in reality, he's a manipulative sociopath with a growing body count.

Plot Summary:

After escaping a toxic relationship with the enigmatic Jang Haemin, Seo Mirae is trying to rebuild her life. But as she investigates a string of recent disappearances for an underground article, she starts to realize all the missing women have one thing in common: they all dated Haemin.

Her obsession with uncovering the truth brings her to Kim Yeon, a criminal profiler who has been silently tracking a killer dubbed "The Architect"—a predator who builds elaborate psychological "traps" for his victims before they vanish without a trace.

Together, Mirae and Kim Yeon begin to piece together a chilling picture: Haemin's obsession with control has evolved into something far more deadly. He doesn’t just want love—he wants ownership. He builds "perfect" realities for his victims, trapping them in their own minds using fear, manipulation, and hallucinations until they either comply... or disappear.

As Mirae gets closer to the truth, Haemin begins to insert himself back into her life—text messages, unexplainable break-ins, and the haunting feeling that she’s constantly being watched. Kim Yeon’s own secrets begin to unravel too, and Mirae must decide: can she trust this quiet, haunted man? Or is the line between protector and predator thinner than she thinks?

Chapter One: The Mirror Cracks

Seoul pulsed under the dying light of dusk, its skyscrapers like blades cutting into the bleeding horizon. Inside a high-rise café in Mapo-gu, Seo Mirae sat alone, her fingers wrapped tightly around a lukewarm mug of black coffee. Her eyes flicked across her notebook, pages cluttered with names, dates, and red circles. Seven women. All missing. All vanished without a trace in the last nine months.

And all of them once loved Jang Haemin.

A shiver ran down her spine. The name still clung to her like smoke—sweet at first, then choking. Haemin had been everything at first. Polite. Gentle. Attentive. Almost too perfect. She remembered the roses he used to send—always twelve, always blood red. He said they were a symbol of “eternal love.”

But love wasn’t what he gave her.

It was control, wrapped in soft-spoken words and well-tailored suits. The emotional bruises lingered long after she ran.

Now, a journalist barely scraping by, Mirae found herself circling back to the past she swore she’d buried. Each article she pitched about the missing women was rejected. "No proof," the editors said. "Sounds like a conspiracy theory." But she knew. In her gut, she knew.

A shadow fell across her table.

“Seo Mirae-ssi?”

She looked up. A tall man in a dark trench coat stood there. Pale skin, a faint scar near his jawline, and dark eyes that studied her like a chessboard.

“I’m Kim Yeon,” he said quietly. “You asked for a profiler.”

Mirae hesitated, then nodded. “Sit.”

He did, removing a small black notebook from his coat. “You said the same man may be connected to all seven disappearances.”

“Not may be. Is.” Mirae’s voice sharpened. “They all dated him. He isolates them. Then they vanish. Same pattern. And no one’s doing a damn thing.”

Kim Yeon didn’t flinch. “Why now?”

“Because,” she whispered, lowering her voice, “he’s watching me again.”

She slid a photo across the table.

It was her apartment door—fresh scratches along the lock. Not forced, just… touched. Beneath it, a single rose lay.

Kim Yeon picked it up with gloved fingers. “Classic control behavior. Keeps you uncertain. Anxious.”

“And no fingerprints,” she added. “He’s careful. Smart.”

Kim Yeon nodded. “Jang Haemin is more than a narcissist. He fits the profile of a compulsive psychological captor.”

“A what?”

“Someone who doesn’t just trap people physically,” he said. “He builds mental prisons. The kind you can’t escape even when you leave.”

The words chilled her.

Then his eyes narrowed. “Mirae-ssi, have you told anyone else about this meeting?”

She frowned. “No. Why?”

Kim Yeon flipped his notebook open. On the first page was a polaroid photo—old, blurred—but clear enough.

Her face. And a caption scrawled in red ink:

"She belongs in the glass house next."
