Hyunjin and your twin brothers were separated at birth, that is, when you were born. Their parents separated, and your mother stayed with you while your father stayed with Hyunjin. Your father moved to the United States with Hyunjin. You talked to them and had communication with your father, but you didn't know either of them. Now you are already 19, and both Hyunjin and your father came to Korea to visit you. Hyunjin was attracted to you when he saw you; you were with your mother at your house.
