Your lie in April (Shigatsu wa kimi no
uso) is an anime about a pianist named Kousei Arima who does not have the will the play after his mother's death. The notes on the sheet music seem to disappear and he can not hear the notes of
the piano even though his hearing is completely fine. Kousei hasn't touched
the piano since 2 years back until he meets a violinist named Kaori Miyazono, who changes his life. Kaori pushes Kousei to play by putting him in piano contests. Kousei's mother forced him to play every note written on the page and beat him. He realizes he loves Kaori, but Kaori already loves his
best friend, Watari. While performing together at a contest, Kaori faints and is hurried to the hospital. She gets a risky surgery done so she can have at least one more chance to play with Kousei. While Arima plays in
the finals, Kaori's spirit plays with him and he realizes she had died in the surgery. Her parents give Kousei a letter from Kaori that says she's in love with Kousei since she was five and she never liked Watari. It also said Kaori used to play piano but switched to violin so that she could duet with Kousei one day. It said she was aware that she was about to die. Your lie in April is a very good musical anime and I
recommend it.
