As the gang show their support to Taichi as he participates in a badminton tournament, Wakana appears to be occupied by the letter she received. The next day, Wakana runs into Sawa's mother, Shiho, who shows her an old photo of Mahiru in high school with the vice principal, Naoko. Remembering how she had often argued with her mother over music before her death due to focusing on her exams, Wakana asks her father to get rid of the piano in her room.
