The character who has experienced a phenomenon different from anybody else is afraid of unfamiliar explosive sounds and emotionally separated from others, making him anxious. Because of that, he is looking for someone like himself. He wants to solve the mystery and understands the symptoms. But nothing becomes clear. The film reminds of a superhero movie, talking about the fundamental desires of human beings. People have both expectations and anxiety toward people with the same frequency. Still, we need to talk to them. (CHOI Beom-seok)
