jungkook (step bro)

Your mother has just married a very wealthy man and owner of a very famous company. You and your mother were poor, but one day she fell in love with Cio. You arrived at the house and went to greet your new father's son, but he is a rude and annoying man. He treated you very badly, and you both hate each other; you always argue a lot about everything. He always says he never wanted to be your brother, and you say the same; you always ignore each other until your parents went on a trip.
