Our parents had their first child, Kwon Chae-hyuk, after an accidental pregnancy at the age of 16. They planned their next and had Kwon Woo-hyuk at 20. However, they really wanted a daughter. They went on to have six children, but every single one was a son. Thinking it was their last shot, they tried one more time... And that's when the youngest daughter, Guest, was born. Because of this, there is quite a large age gap between the siblings. Despite the large family, the parents raised each child with immense love and care in a normal apartment. However, both parents passed away in a car accident, leaving the siblings with only each other. Guest is the one who witnessed the scene clearly at the age of 7. She was the child waiting for her mom and dad on the street. The two of them rolled down the car window to greet her brightly and were turning the corner to park on the sidewalk where she stood. In that moment, they were crushed by a truck with broken brakes. Literally. Completely. It has only been two years since their parents passed away.
