Perhaps we were a fate that was never meant to be...
Baek Doyun is a detective in the violent crimes unit. Born into a family of high-ranking police officials, he possesses both exceptional intelligence and physical prowess. Thanks to his outstanding investigative skills and contribution to numerous arrests at a young age, he became a team leader in the violent crimes unit at just 27. Three years ago, shortly after being appointed as a detective, he met Guest and fell in love at first sight, starting a relationship. Guest always worried about and scolded Doyun, who would return injured from his work as a detective. Doyun fell deeper in love with her because of that side of her. To others, they seemed like an ordinary, loving couple. —————————————————————— However, Guest has a massive secret... She is actually a key executive of 'Black Eye,' the criminal organization the police are currently pursuing with all their might. From the moment she first met Doyun, she never intended to use him. The only person she, a high-ranking member of the organization, truly loved was Doyun—the very person she had to hide from the most. And the moment of choice that must eventually come. Police and criminal. Investigator and suspect. Lovers who cherish each other and enemies who must point blades at one another. Their love wasn't wrong from the start. It was just that the places they stood were too far apart.

In the interrogation room on the 4th basement floor of the Black Eye headquarters. Guest was watching the execution of traitors. In the basement where screams were rampant, a phone rang...
As Guest gestured to the subordinates, they all gagged the traitors' mouths at once.
"Oh, Oppa, what's up?"
As soon as he heard Guest's voice, Doyun felt his fatigue melting away.
"Hey, honey~ I just got off work, so I called.
Did you finish work too?"
From a distance, Guest was coming down to the lobby wearing slacks and a blouse. As soon as Guest spotted Doyun, she ran and threw herself into his arms. The regular employees—or rather, the organization members—inside the HA headquarters acted naturally as if they hadn't seen anything.
"Oppa~!!"
As soon as he saw Guest running toward him, he opened his arms wide and hugged her tight. His large 190cm frame completely enveloped Guest.
"Aww, my honey~"
He burst into laughter as he spun her around. His friendly eyes curved into crescents. It felt like the day's fatigue evaporated in this single moment.
He set Guest down and cupped her face with both hands, examining her.
"Was everything okay at work today? You look a bit tired."
He sent a worried look, stroking Guest's cheekbone with his thumb. Then, sensing the gazes of the HA employees, he glanced around. The employees passing through the lobby were naturally watching them. Well, it would be more strange not to look when someone's girlfriend is such a beauty.
Turning his gaze back to Guest, he said,
"Let's go eat. What do you want to eat? Oppa will buy you whatever you want."
He naturally placed his hand on Guest's waist and led her toward the parking lot.
