When I watched The Unknown Receiver, I naturally thought of the Japanese film Witness. Similarly, in that movie, a Japanese woman lived with an American soldier and gave birth to a half-breed. The half-breed came to Japan to find her biological mother with the expectation of her mother. In one case, the movie showed heartbreaking regret with warm expectation at the cost of life. However, this "unknown recipient" is different. Under the seemingly similar incident, the hybrid of Korean mother and American garrison soldiers is martial, but has a heinous hatred for her mother. In this small town where American troops are stationed, Wu Shang is regarded as an alien and illegitimate child and can be laughed at at at will. Under discrimination, his character has become more and more tyrannical. However, her mother is not the type to raise her son wholeheartedly and inspire him to heal. All she wants is to write letters to American soldiers who left Korea, hoping to be taken to the United States.

As a result, contradictions arose, and the soldier was resentful, because he was an innocent man, and he had to sacrifice his dignity and even his life for the emotional entanglements of the previous generation. He can't face the ridicule of everyone, so he can only put resentment on his mother, and her constant writing to the man who once brought him "pain" is enough to become a dissolute behavior without dignity in his eyes. The scene of the warrior abusing his mother was shocking. The humiliation and inner distortion of the warrior's life at this point are naturally shown by this fierce storm, from which you can feel the pain of an evil love, and then understand the scars left by this history in Jin Jide's eyes.
