Theme
Gang-du's father Hie-bong scolds him for his incompetence, saying "You're not all there" - establishing the theme of underestimation and the need to see past surface limitations. The family's dysfunction and low expectations for Gang-du frame the story's central question about worth and capability.
Worldbuilding
Introduction to the Park family dynamics: Gang-du's brothers Nam-il (unemployed) and Nam-joo (archer) arrive, revealing family tensions and individual failures. The Han River setting is established as both livelihood and lurking danger, with casual mentions of pollution and strange sightings.

They cross from passive victims into active rebels against both monster and government.
Mirror World
The family works together in the sewers with newfound unity and purpose. Hie-bong treats Gang-du with respect for the first time, trusting his instincts. This collective mission becomes the thematic counterpoint - the "useless" family members proving their worth through loyalty and determination when institutions fail.
Premise
The family navigates the sewers searching for Hyun-seo while evading military forces. Meanwhile, Hyun-seo survives in the monster's lair, protecting a young boy. The "fun and games" of this monster movie: tracking clues, close calls with the creature, family arguments and bonding, and the darkly comic ineffectiveness of both the family and authorities.

Collapse
Hie-bong, the family patriarch, dies from Agent Yellow while trying to attack the monster with a rifle.
