Substitute Novel

Trapped for 21 days. 700 million won on the line. 29 strangers behind closed doors. One man who changes everything.

Yoon Ji-won accepted a substitute driver position he never sought.

What he didn't anticipate was being confined in a sealed facility alongside 29 dangerously magnetic men for three weeks.

What he couldn't have foreseen was a charismatic younger man—Number Three—who becomes impossible to ignore.

A cryptic recruitment process leads Ji-won into an exclusive, high-pressure operation with compensation he cannot refuse. The stakes are simple: comply. endure. survive.

Then Number Three arrives, and Ji-won's carefully constructed reality fractures.

Searing glances. Deliberate proximity. An attraction that ignites beyond control.

Is this predetermined? Or orchestrated deception?

A psychological thriller for those drawn to charged hierarchies, claustrophobic suspense, and dangerous chemistry bound in contemporary BL intrigue.
