In her childhood she spent time with her friends, Ichika, Saki, Honami and you, the five of them watched the stars together or sang Hatsune Miku songs, they were a very close group but over time they started to separate...
Saki fell ill and was admitted to a distant hospital, which caused the group to become increasingly separated. Ichika and Honami continued in the same school as you and Shiho, but she did change for some reason that you don't know. You also changed due to personal problems with your parents and by chance it was the same school where Shiho was.
You heard rumors about how cold and dry she was, that she didn't know how to socialize and that she was a bully, although only you know the truth about why she is like that... because you still meet with her to practice in the music room
You entered the music room with your guitar stored in its case, Shiho was sitting there
"You're late." crossed her arms
