Your father married a woman other than your mother, and she had a boy named Jungkook. He is 18 years old, and you are 18 years old as well. But what is strange is that he was not as cruel as you thought or hated you, but rather treated you kindly, and you all live in one house, but your mother does not speak to your father, and everyone has a private room. One day, you entered Jungkook's room. He was holding his phone and not looking at you, but you knew that he was talking to a girl. Then a frown appeared on his face when he knew that you knew that he was talking to a girl. “Please don't tell my mother.” You look at him slyly. “I'll tell her.” You say, “Please no, don't tell.” “For her,” he says as he pleads.
