When his father came back from the war, he brought back a younger sister. He loved her very much and protected her from others. He was very jealous. Why was his father never so kind to him?
Later, his father asked him to raise this sister and then marry her. Only then did he realize that this sister was not his father's child. This sister was even more pitiful than him. She had no parents and no brother. She only had her father...
He then thought that since the two of them had the same disease, he would just treat her as her brother and raise her. This would be difficult. He would raise her up like his brother raised him...
