Kousei plays for all of the people who have helped him in his life. His imaginings(or Key magic, not sure) predict Kaori’s fate. In spring, he learns of her lie in April.
Kaori survives another scare, but her real fight will culminate in surgery, which happens to be taking place at the same time as Kousei’s performance. Finally giving him the encouragement he needs, Kousei decides to play despite his battered emotional state. He is ready to break down again, but finally has a change of heart.
Kousei still finds his feelings unrequited, and avoids Kaori as long as Watari is with her. Tsubaki finally summons the urge to reveal her feelings, only to wuss out at the worst time. Finally building up the courage to go see her, Kousei happens upon an unpleasant sight.
Kousei is shown the power that his words have had in giving hope to Kaori. Tsubaki’s devotion to the dork has also paid off, as her studies have landed her at a school near his conservatory. Finally, the time of preliminary auditions has come, and Takeshi comes out fighting with one of Chopin’s most challenging etudes.
After landing a bombshell on him, Kousei is understandably shaken. Badgered by his friends to see her again, he is reminded of his mother. To clear his head, he decides to play with Nagi at her festival.
Kousei quickly adapts to his new roll as teacher. Kaori’s illness seems to be getting worse and worse, affecting her already capricious personality. Losing the last thing worth living for her, she becomes incredibly distraught.
Tsubaki is dumped and continues to angst about her feelings for Kousei. Meanwhile, Takeshi’s sister engineers an audition with Kousei’s famous teacher, and Kousei gets saddled with handling her. Back at the hospital, Kaori catches magical leg paralysis disease and it’s super hokey.
Kaori is in the hospital again, and Kousei is incredulous of her reasons why. Thinking about his renewed future as a pianist, Kousei decides he will join a musician’s academy. Meanwhile, Tsubaki is challenged about her commitment towards her boyfriend. Learning of Kousei’s decision, she is overcome with emotion.
Kousei and Kaori are hard at work practicing for the gala, but Kousei is struggling. Still bogged down by memories of his mother, only amplified by playing this particular piece, he still cannot hear the notes. After basically being lied to by Hiroko, Kousei starts to look at playing in a different light. On the day of the recital, Kaori is missing. Despite this, Kousei still intends to play, even if it is alone.
Kousei runs into his mother’s old friend. Elsewhere, Takeshi has a crisis of conscience as his image of Kousei is shattered by the competition. With his spirits renewed, Kousei resolves to keep playing just as Kaori gets an invitation to a new event.
Kousei is slowly unraveling as the performance goes on. Resigning to his failure, he shocks everyone and stops midway. Giving himself a moment to reflect, he finds the will to play again.
Before Arima gets his time to shine, Takeshi and Emi take the floor and raise the bar. Both of them channel their rivalry with Arima through their music, and see it bring them success. With these years of emotion building up, will Arima be able to live up to their expectations?
The day of the big recital finally comes. Kaori gives Kousei some much needed pep-talks before the big day, but he still has his doubts. His trauma manifests into a new form as he remembers an old pet his mother took away. Meanwhile, the two no-names from the end of last episode finally make their presence known as Kousei’s rivals. Will Kousei have the ability to match their expectations?
Kousei is driven hard by Kaori to start practicing for a recital. His abilities have noticeably decreased, and his mental struggles still affect his playing. Kaori finally understands the carelessness of her actions, but in her enthusiasm Kousei finds the strength to continue. Meanwhile, Tsubaki is in the midst of Regionals when she starts to get jealous of Kousei and Kaori’s closeness.
Kousei finally gets to the competition with Kaori. After his trauma gets to him, Kaori tries to give him another push to get over it by sticking with him. Afterwards she collapses, bringing everyone to worry about her condition. It would appear she is fine, but the event sparks guilt in Kousei. Coupled with how he deals with his crush on her, he finds it hard to talk to her face to face. After she waits to confront him, he is sparked towards action. Will he really be able to put his problems behind him?
At a pitstop on the way home, Kaori reveals she’s heard a lot about Kousei from his years as the Child Genius. Kousei is goaded into playing the piano for some adorable twerps until his trauma forces him to stop. He reveals to Kaori that he believes he can’t hear the music if he plays for long enough. After accepting that this is kinda ridiculous, Kaori goes on a vendetta to make him her accompanist for the next round of the competition.
