Almost all roles in this film are named (because most female roles are Gods) but there is no scene where they are talking to each other, because they all live in their own areas.
Deok-Chun, a newbie grim reaper always walks with Ja-hong (main character) and only talks within her work group with two other men.
Jahong’s mother is mute for most part of the film and does not interact with another female. When she finally speaks in her dream, she’s talking to her son.
