However, her life turns upside down as two of those friends, Mai Ouzuka and Ajisai Sena, have confessed their love to her. While mulling over what to do, Renako discovers another member of their group, Kaho Koyanagi, is actually her friend from elementary school!

But with the confessions still weighing on her, and Kaho making her own moves, Renako has to make up her mind—and fast!
