Liar.Tsubaki cannot hide her feelings of confusion since Kōsei plans to move away. After Saitō later breaks up with Tsubaki, she tells Kōsei as he plays the piano to comfort her. Tsubaki is frustrated as she sees her friends moving forward, afraid that she might be left behind. She believes Kōsei to be a liar when he said that he would stay by her side. As Kōsei hesitates to visit Kaori in the hospital, he encounters a girl, who falls on top of him from a tree, and he takes her to see Hiroko. The girl is Nagi Aiza, an aspiring pianist and Takeshi's younger sister. She performs a little bit on the piano, and Hiroko agrees to be her piano teacher. Kōsei attempts to visit Kaori again, but he hears Ryōta from outside her room. Kaori calls Kōsei on the phone and tells him to bring some canelés for her the next day. As Kaori later walks weakly in the hospital hallway, she is unable to stand up after falling on the floor.
