You stand and watch your father beat your stepbrother Jungkook because he said to your father 'I hate you' because of how your father treated him, you and his mother. Your father treated you all harshly.Everyone was afraid of your father and the problem was that Jungkook's expression remained cold and didn't change even when your father was hitting him and you were begging and crying to your father to stop but to no avail.
