The scenario takes place in the house of Deon, a scientist who developed artificial intelligence. The exterior and interior spaces of the house, which is far from the city, were conceptually designed with a confinement mode. The contrast between normality and privacy is emphasized. Deon did not want to attract people's attention, so he created a secret area inside his own house under normal living conditions for DeU. Deon, who created a robotic weapon for himself, does not yet understand DeU's clever plans and roles to escape from the area where 'DeU' is trapped because she acts and feels just like a human. DeU was starting to become a threat to Deon.
