Air on the G String

Summary

Haru is skipping school after seeing the person who was the cause of her transfer during middle school. She has also been absent from club activities. Ritsuko's concerned message to her is answered only by the words "I'm fine". These words are like a curse for Haru, but she can't tell Ritsuko how she really feels even though she considers her a kind person. Ritsuko remembers the promise made between the two of them that they would play violin together in the school orchestra, and decides to take action.
