Originally the setting was that the two cook and eat rice together. It was changed to potatoes for a more realistic setting. This scene is a scene that contains the specialty of director Hur Jin-ho, a master of melodrama.
However, as the movie added drama to its actual faction, he tried to capture the melodramatic atmosphere while keeping the line to some extent with a scene in which Kim Jang-han (Park Hae-il) and Deokhye (Son Ye-jin) stay in a mountain cabin, cook and eat potatoes together.
