The film represents age and gender in the following ways:
1) The main character is meant to be 30 years old but is portrayed by a 17-year-old actor, making his age unclear. Older people are depicted as more unpredictable and lonely.
2) Only masculinity is represented, with no female characters. The male main character is portrayed as quiet, fearful, independent, and lonely, showing men as broken and frightened rather than typically strong.
3) Mise-en-scene like the character's dark clothes help convey his withdrawn and mature personality. Details in appearance are used to determine the character's personality.
