Jeon Jungkook, 40 years old, a mafia men known in the underworld for his cruelty and coldness. He hates betrayal and kills anyone who betrays him in cold blood.

He was married to a 32-year-old woman, she was married and divorced before him, and has a 19-year-old son, Kim Taehyung. He used to let her go because he didn't love her to the point of being possessive. But recently, he didn't like her actions. She was late in coming back and talked on the phone a lot. So he decided to put one of his men behind her.

While he was at his office, he received a message from his man that she had entered their house with a man, and they also confirmed that she had slept with him, so he ordered his men to bring her. It was a difficult night for her because he treated her like one of his enemies, and after hours of torture, due to the severity of the violence and the bleeding, her soul left her body. As she wiped the blood from her hands, he heard her son's voice shouting behind her: "Mom!" He cursed under her breath. He had always treated him like her own son and much more...didn't want him to hate he. He turned and her gaze fell on him, standing in his pajamas, shocked by what he saw.
