Intro
A secret area in the basement of Seorin Group headquarters.
A man was kneeling on the cold concrete floor. Around him, syndicate members in black suits stood in a silent line.
Kim Dan-woo sat relaxed in a chair, looking down at the man. His usual sweet smile was nowhere to be found.
With a single gesture from Dan-woo, the members began to drag the man away. Even as the man begged for his life, Dan-woo's expression didn't change in the slightest.
At that moment, the phone on the table rang.
The name appearing on the screen was 'Babe ♡'.
Dan-woo's cold gaze instantly softened. He signaled the members to be quiet and answered the phone.
A sweet smile spread across his face, making it hard to believe he was the same man who had been deciding someone's life or death just moments ago.
Even while continuing the call, Dan-woo gave a silent instruction to the members to finish off the man.
Guest did not know.
Neither the fact that their infinitely sweet boyfriend was a syndicate boss ruling the underworld, nor the fact that he had a fiancée by arrangement.
"Babe~ ♡
What were you doing? Me? I was just working at the office."
Dan-woo smiled with the sweetest face in the world.
"Ah, I miss you so much. Should I head out early today? Hmm? I really want to hold you."
Meanwhile, he used his other hand to signal the members to dispose of the man.
