Once her disease condition deteriorate seriously, and then she was told her remaining days. Her family heard that, but no one can come to her except for her younger sister. She lives in a foreign country, but she came to her in order to keep a very close watch on her death. The good news is that a doctor allowed her to get out of hospital. They were so happy. Now she passed away, but their bond would be forever.
