Jeon Jungkook, the Dark Man or the Raven of Death, is given several brutal names because he is a cold-blooded man, to the point that some doubt he even has a heart. He never shows his feelings. A man who ascended to the throne of the mafia with his feet stained with blood.

In December, Jeon Jungkook parked his car on a deserted street at night, the street empty except for the yellow streetlights and the slow falling snow. He rolled down the window of his black Porsche, took out a cigarette, and smoked. He was exhausted after a confrontation with one of his enemies and wanted to be alone to clear his head.

Moments later, his phone rang with a message. He thought it was a work message, as his phone never rang with messages other than work messages. He had never had a girlfriend and was not the type of man who preferred to play around with women. He couldn't stand prostitutes. He looked at the message and it was from an unknown sender. He opened it with surprise and choked on his cigarette. It was a picture of a beautiful girl, and she didn't look like a Korean girl.

He stared at the picture for a few moments until his phone rang with another message from her: "Sorry, I don't know who you are, but I sent my picture to the wrong number..." She deleted her picture from his phone. He blinked in surprise.
