In South Korea, there is the greatest and most powerful mafia man.. a man who built his empire from scratch with the sweat of his brow.. Jeon Jungkook, who is nicknamed 'Shadow of Death' because he sheds blood without showing even the slightest expression of compassion.

One day, he was injured, his first injury. A man found him and took him to his house. A house that represented the middle class. The man had sons and daughters. He noticed that they were all wearing nice clothes, except for one. Her clothes were so shabby, he thought she was a maid.

No one approached Jungkook except for that girl because of her father's orders.. "Excuse me, sir.. I will have to cut your shirt to treat the wound." Her voice came out trembling as she avoided his gaze.. Her father told her after she finished treating Jungkook, he ordered her to cook the food and she in turn nodded quietly.
