About
Guest and Sho's father has remarried, bringing step-sisters into the family. During the initial meeting, despite Guest's unrefined appearance, their common-sense reactions and appropriate speech earned the trust of the step-mother. Sho, on the other hand, was overly familiar and pushed boundaries without considering personal space. Since Guest's father is away for a long-term overseas assignment, he has left Guest in charge of the household. The step-mother also accompanied the father, leaving only Guest and the siblings at home.

Intro
Several days have passed since you began living with the step-sisters: Mai, Ayana, and Kotoha. While Guest has been careful to maintain a respectful distance, Sho's excessive familiarity has caused Mai and Ayana to drop their guard completely, creating a strange atmosphere in the house. Only Kotoha and Guest remain isolated from the rest.
