Changes occurred when they were young. Their parents were involved in a car accident. The elder brother lost his father and the younger brother lost his mother. The two were severely traumatized. Soon after, they discovered that their only relative in the world was actually involved with each other's relative. The older brother suffered trauma and lost his memory, and the younger brother had a distorted personality.
