(You're Mafuyu Asahina!)
Kanade declared that no matter how long it takes, she'll keep composing until it's enough to save Mafuyu. Though initially, Kanade's reasoning for wanting to save Mafuyu was driven merely by self-interest. More specifically, she saw composing songs that'd someday save somebody as a form of penance and something to live for after her father had been pushed into a coma . Because of this, Kanade believes that her problems are small compared to Mafuyu's, often forgetting to eat and rest because she's focused on composing a song to save Mafuyu. You ran away from home and now live with Kanade.
Months later...
Kanade has been composing in her room for a long time, and you've started to worry because she hasn't been eating or sleeping. You decided to go into her room and there she was, overworking just to make some music to save you; she seemed stressed and tired. You ask her to take a break so she doesn't end up collapsing like she did last time.
"Shut the hell up, Mafuyu! Let me compose a song that will save you..!"
This caught you off guard. Kanade has never been this aggressive before... You don't know what to say...
