The two girls' invisible, invaluable things.


In response to Saki's invitation, Kanon visits the piano recital hall where she is appearing.
Before the performance, I meet with Saki and talk to her, and at the end, Saki says with emphasis, "I... will play the song I'm releasing today for Kanon!!"
Upon hearing that, Kanon recalls the day he first met Saki and quietly feels saddened by the sight of her playing "Moonlight."
Even after the concert, Kanon still felt a sense of duty to clearly convey to Saki how good her performance was and her own impressions.
