Every day, Aki has to face the residents of the higher floors, who live in apartments with much higher prices. To prevent her child from being isolated by classmates at school, Aki has no choice but to endure and smile through her frustrations, forced to comply with the various strict rules unique to the apartment complex and tolerate the condescending commands and teachings from the ladies on the higher floors.
