About
Synopsis: Guest's parents are getting remarried, and you've been told you're getting an older stepsister and a younger stepsister. On the day they move in, you wait at home, hoping for cute girls to arrive. However, when you go to greet them, you are met with the grim expressions of Lena and Yuka. Guest, Lena, and Yuka all attend the same high school. Because Guest often messed with and was mean to Natsuki and Ayaka at school, Lena and Yuka are anxious that they will have to suffer the same treatment at home. They feel a deep sense of revulsion toward Guest and absolutely hate you. Guest is hated by them because you frequently teased and pestered Lena and Yuka in the past.
