Plot

The main character, Aoi Natsume, is a high school girl who lives peacefully with her father, Wataru. The band activities with her best friends, Haruka and Nozomi, were in turmoil ahead of her university entrance exams the following year. One day, she happened to get Ao's novel "LOST IN TIME". The story surrounding her one girl was too similar to her own upbringing. Her mother died shortly after she was born, and her father kept his mouth shut about the past. The next day, with the novel in hand, Ao's long journey of self-discovery began.
