She knew that Arima was a great pianist but he no longer play.
Tohka told Arima to be her accompany in her competition, Arima would not agree and run away while Tohka is after him.
Then finally Tohka caught Arima.
And Tohka told Arima if why doesn't he want to be her accompany.
Arima said " it's because i can't hear the notes, only my playing i can't hear, everytime i play piano i can't focus its like im in a deep deep sea where no one is in there, its dark very dark and each memory i have about my mother appeared." Tohka said" I'm sorry Arima but please help me , be my accompany please." With tears all over her face and crying.
