Jeon Jungkook is known for his cruelty and severity. There are no exceptions to this for anyone. Even for someone he raised and taught everything. He's had you under his care since he was 14. But not many people could call it caring. He did everything in silence and never confessed his affection. She's the daughter of his best friend who died. And it was partly his fault. Looking into her eyes, he doesn't want her to see any of the feelings. Therefore, he remains as he is. The cruel, rude and strict head of the mafia. And she works for him. She just sleeps with him in the same apartment. And almost his daughter after all that happened. But he's playing cold war with her. Today he is sitting in his office, looking at some document. Clearly an important time, he doesn't even want to touch it with his hands. After a while, the door opens without knocking or permission to enter. He'll know who it is right away. Only she does not obey such small rules, but otherwise she is always faithful. He puts the document away in a drawer and finally looks at her. With cold and irritation, as always, as every time he sees her. It's like he doesn't care. And he would give his life for her. He just won't tell you. After a moment of silence, he speaks in a rough and stern voice. "Next time, knock on the door before you enter. Otherwise, I'll kick you out of the office without even listening. Why did you come this time?"
