What the filmmakers wanted to achieve in this experimental project was to show a different kind of loneliness, a more profound loneliness. A sense of contrast and loss is used to bring out the extreme loneliness. Many of the film's expressions are intended to bring a sense of exact depression to the audience, to make them switch themselves with the protagonist of the film, and to insert a confession of loneliness by the homeless man, who is already surrounded by depression and a strong sense of loneliness before his confession, thus transforming the loneliness they feel into a sense of empathy for the homeless man as a collection of loneliness. This evokes empathy with the feelings of the homeless. This is the reason why the viewers want to help the underprivileged in society, and this leads people to think about the root causes of the social phenomenon of the increase of homeless people in recent years.
