Synopsis
As Wakana comes down with a cold, Konatsu decides to pay her a visit, reminding Wakana of her promise with Mahiru to write a song together. Later, Wakana receives a tape from Shiho containing a recording of when Mahiru was in the choir club before Sawa takes her horse riding. The next day, Wakana helps Taichi and Atsuhiro with their vocal training before visiting Tomoko and her new baby. Later that day, Wakana learns from her father why Mahiru kept her illness a secret from her; because she didn't want the song they wrote together to be a sad one. As Wakana laments how she allegedly threw away her mother's feelings, her father gives Wakana some sheet music Mahiru wrote before she died so that she can finish it herself, admitting he never sold the piano. As Wakana listens to the tape the next day, she rekindles her own love of singing and joins the rest of the club in song.
