The Japanese novel Scar, known as the Heroes of the Three Kingdoms in South Korea, is a well-known work, and Teenagers Don't Cry is a film based on Scar. Scar describes the story of two teenagers fighting for survival in chaotic Japan after World War II. The ruined scene of South Korea after World War II is very similar to that of Japan after World War II, so the production company decided to shoot a film based on Scar, and restore the original appearance of human beings through the image of children struggling with the suffering left over by the war. With this intention, the film began to enter the planning and development stage. The planning company first found the screenwriters Han Zhixun and Sang-don Kim of Flying Taiji Flag, and they wrote the script with 1953 postwar Seoul as the background. This film focuses on the best talents in the Korean film industry, and * * * has created this real and tragic war film.
