Farewell (2013)

Fifteen-year-old Myung-hee and her nine-year-old brother Myung-ho are of Korean-Chinese descent. Their mother left for Yeonbyeon three months ago, promising to return with their father, and they have heard no news from her since. Every day, Myung-hee and Myung-ho go to the shipping port or airport hoping for their parents' return. Tired from waiting one day, Myung-hee meets Yong-kyu, a young man high from sniffing glue. Beyond a tough and violent exterior, Myung-hee finds a young man's heartwarming inner-self, and she expects Yong-kyu to take the place of her parents. But even Yong-kyu leaves her and life steadily deteriorates. Hoping for help, Myung-hee goes to a familiar Korean-Chinese woman, arriving in time to find immigration officials taking the woman away. They are now truly alone.
