Once upon a time, there was young, black-haired boy with thick glasses by the name of Kousei Arima. It all started when he was a little boy, when his mother, Saki's friend, Hiroko Seto found something special in the boy when he recreated a song called "Idiot Husband"/"Hubby is a Dummy" that Hiroko played, much to the frustration of his father, Takahiko.

From there, the little Kousei cultivated himself into one of the best piano players in his school. Unfortunately, one side effect of him honing his talents is that he became much more distant between his old friends Ryouta Watari and Tsubaki Sawabe, who were athletes that played soccer and softball, respectively.

While Kousei's mother, Saki was a very loving mother, she also was, at the same time, an utter perfectionist who demanded nothing better than to have his son be the best. She had trained him to become almost like a machine when he played the piano.

As a result of this, Saki and Kousei shared a rather bipolar relationship, beating him for even the most minor of mistakes. They would get along one day and be like cats and dogs viciously fighting the next. She was just cruelly abusive towards him on such days like that, and her words were as cold as ice.

Around the time Kousei was seven, Saki became terminally ill. Things reached a breaking point one day, when the seven-year old Kousei entered a competition and performed very well. Saki had come from the hospital to watch him, but she was not satisfied with his performance, because she had felt he had not played the score the way it was written.

Saki took out her anger on the little Kousei, and this led to the wheelchair-bound Saki's friend Hiroko intervening with Saki to stop.

Little Kousei was scared to death and started sobbing; he had been beaten so badly, he needed some medical attention. Hiroko was NOT having any of Saki's borderline-evil attitude. Hiroko successfully stopped Saki from beating her son further. Saki had beaten her own son pretty badly.

When it was all said and done, an angry Kousei said "I wish you'd just die, mom! I'll never play the piano again!" Of course, while Kousei would continue to play the piano, his wish of having his mother die ultimately came true, much to his surprise and shock, as she died shortly after this incident.

Saki's death deeply affected Kousei, and he regretted ever for wishing such a horrible wish on his mother, in spite of their Jekyll-and-Hyde relationship. Of course, his mother's disease was hereditary, so at this time his condition was diagnosed as anemia, when your iron levels drop and make you eventually pass out, something that Kousei himself would not know he would have for a long while. However, it would turn out to be something much worse......

Kousei then had a p
