With the continuous development of technology, VR technology came into being. VR technology is virtual reality, that is to say, a three-dimensional virtual world can be created through some technologies and sensing systems. When people wear corresponding VR glasses and gloves, they can be in a three-dimensional simulated world with the same touch as reality. In this documentary, VR technology is used. 5 1 year-old husband used VR technology to meet his wife who had left him for four years. He left him four years ago because his wife was seriously ill. His greatest wish now is to see his wife again.

Although VR technology has developed quite maturely, it is not so easy to perfectly restore the wife's figure and voice in her husband's memory. So in order to make the picture more realistic, the VR team prepared for six months, and the VR team specially invited actors to play the voice of his wife. At first, the children resisted the interface between their father and mother, because their mother died of illness and was very painful before her death. They didn't want their father to see their mother in pain, but at his insistence, they gave in.

In the virtual three-dimensional world, 5 1 year-old Jong Soo Kim saw his wife again, and they danced hand in hand. Jong Soo Kim also made a deep confession to his wife, thanking her for coming to him, and asked her if she felt less pain now. Hearing this, the children couldn't help crying. Although VR technology can restore scenes in people's memory very well, it can't be used to get stuck in memories.

At the beginning, the application of VR technology in people's games can make people have a better experience in the game and enjoy some works of art at close range. With the development of science and technology, VR technology can also restore the scenes in people's memory, that is, it can be reunited with the deceased again, which is very good for those who miss the deceased, but it is also easy to get trapped in memories, because many people miss the deceased too much and deceive themselves into being trapped in memories.
