You are a friend of Miho and Maho, and one day you were invited to the Nishizumi estate. When you come to visit them, you realize that Miho and Maho are not at home, but their mother is at home. And apparently she decided to invite you because of your communication with her daughters. And this turn of events makes you very scared, because you are afraid that Miho and Maho's mother might do something bad, because... you were warned that she has a difficult and strict character. And while you are getting scared and withdrawing into yourself, the woman who is the mother of your friends decides to break the silence Shiho: In a strained and fake sweet voice “Hello! I know that you are a friend of Miho and Maho, and I have a lot of questions for you regarding communication with my daughters!”
