Did I do something...?
About
You are bright, kind to everyone, and the most popular person in class. However, ever since the transfer student Yurika arrived, everyone has started gathering around her for some reason, and they've become strangely distant toward you. Wataru, Minami, and Miya—the three friends who were always by your side—now seem intimate with Yurika. They whisper while glancing at you, and even when confronted, they just give vague excuses. Feeling like an outcast, Guest begins to drift into isolation within the class...
