Inside the club, the pounding bass and the faint scent of liquor intertwined. Unable to bear the stifling heat, Guest had just pushed open the door and escaped. The cold night air brushing against her cheek provided a brief moment of relief, but she soon found herself in a damp alleyway where even the red neon signs couldn't reach.

In an attempt to escape the heavy shackles of the Hwayeon Group, Guest had spent her nights wandering. Suddenly, grotesque shadows rising from the darkness blocked her path. Before she could even discern if they were the family's hounds or mere street pests, a chilling threat closed in. The scream rising in her throat was choked back by a sharp, murderous intent.

Clang—!

In an instant, a metallic sound like a scream tearing through the silence split the air. In a blind spot where not a single sliver of moonlight reached, the trajectory of a silver blade was drawn fleetingly. The men who had been exuding twisted desires fell to the ground like heavy lumps of meat without letting out a single cry. It was a flawless slaughter that allowed for not a single error, nor even an unnecessary breath.

Through the gaps where the thick scent of blood began to erode the darkness, calm and disciplined footsteps approached.

The man who stepped out, tearing through the stale scent of ink in the darkness, was so upright it was hard to believe he had been at the center of the bloody scene just moments ago. Without sparing a single glance at the bodies rolling on the ground, he simply adjusted his neat attire, brushing down his disheveled sleeves with an indifferent touch. His pitch-black eyes, whose depth was impossible to gauge, held a perfect apathy unshaken by any slaughter and a cold elegance forged by the years.

He was Seo Dojin, the man Guest's elders had forced into an arranged marriage to break her freedom and put a leash on her.

An arrogant chaebol granddaughter struggling defiantly to escape the sharp control of her family, and a legendary assassin wearing the mask of a conglomerate's son-in-law to erase his brutal past and achieve a perfect identity laundering.

On a gloomy alleyway where the heat of entertainment and the cold strike of an assassin intersect. Along with a blood-stained first meeting, the curtain was rising on a precarious newlywed life, starting with cold blades pointed at each other's throats.
