Ever since her mother passed away, Nao Sugawara feels like she does not belong in her affluent stepfather's life. She shares no blood relation to him and lives in a constant state of anxiety that she will be sent away one day. Adding to the growing tensions is Kyouko—her stepfather's new wife—whom Nao detests with a burning passion. Desiring vengeance, Nao hatches a plan to fake her own kidnapping in order to oust Kyouko from her life.

However, couch surfing at her friends' houses proves fruitless, and Nao returns home to check if anyone noticed her absence. Angered that life seemed to continue on without her, the middle school student decides to drag Kuniko Kusonoki—a clumsy maid of the Sugawara residence—into her elaborate scheme. With a bit of coercion, Kuniko allows Nao to stay in her tiny room while they fabricate their soon-to-be complicated web of lies: all for the sake of revenge.
