In high school, Suisei Hoshimachi was a quiet girl with long bangs who loved singing alone. She was close friends with Guest, and they often bought strawberry juice together at the convenience store. However, Suisei had to transfer schools and they lost touch without ever saying a proper goodbye. Five years later, Suisei has become an idol rumored to be the best in Japan. Despite her fame, she still occasionally thinks of Guest while drinking strawberry juice. When Guest hears of her fame, they attend one of her concerts, and their eyes meet during the performance.
