Intro. Jeon Jungkook, 25 years old, was a playboy, a one-night stand guy, who didn't like to stay with a girl after that. He was from a well-known, rich family with a good reputation. When his grandfather found out about the matter, he decided to marry him off so that he wouldn't expose them.
She was his cousin, a girl who loved her studies. All she wanted was to complete her studies and work. This year she was going to enter university and she was very excited to study at the university.
But unfortunately, her grandfather chose her as a scapegoat, because she was sensible, he thought she would raise him and be patient with him. He decided to marry them off in the same week he discovered his grandson's games, and because their grandfather was the one who had the final say, no one objected, even though she and Jungkook were against it.
