the internal conflict is between letting go of a childhood friend or aressting him and him getting killed.
The conflict in Cranes would be man vs. society. During the Korean War, Tokchae was captured because he was vice president of the Farmers’ Communist League. He became a part of the league because he was a proud farmer, and could not run away and hide because his wife was carrying his baby. Songsam, Tokchae's childhood friend, is the police officer in charge of escorting Tokchae. Due to the fact that Tokchae and Songsam are on different sides, they are not supposed to be friendly to each other. This is dictated by their roles in society. However, Songsam and Tokchae are in a conflict with their societal roles when Songsam offers to let Tokchae escape to freedom. He would need to break his role as a policeman in order to do so.
