One day, when he finally gathered the courage to open that door... After so many years, he had never seen her face again.
Grandfather said there were many children in the courtyard, and he really didn't know which one it was. He begged the doctor who had seen her to take him to find the little girl, but after going through the entire courtyard and seeing all the children, the doctor shook his head at him: "She's not here."
Only after this did he find out that during that time, many families had moved out of the courtyard.
She had also moved away.
He hoped the doctor could accompany him to identify her one family at a time, but his condition improved, and the doctor needed to return to his country. It seemed as if fate had decided that he would never see her again.
He couldn't accept this; how could he go through life without ever seeing that little sun again?
He searched and searched, and years passed, but he didn't even realize it had been so long already.
