Kotoura-san

Synopsis

As Haruka tries to keep the fact she overheard Yoshihisa's confession from him, she and the others go to a karaoke place, where it is soon revealed that Haruka is completely tone deaf. The next evening, as Haruka plans to make a home-made lunch for Yoshihisa, Hiyori has some of her karate members slightly attack Yoshihisa, but it goes disastrously wrong and they end up hospitalizing him. As word reaches the class the next day, Haruka hears Hiyori's stressed thoughts as she fears being found out by everyone. However, Haruka instead chooses to give her some assurance before going to visit Yoshihisa in hospital. After hearing Yoshihisa's thoughts about how he did not want to get Haruka involved, she feels devastated that she is just hurting others in her place and moves away.
