Is Ayu looking for someone?

[Afreek]

well at first in some of her songs such as boys and girls in her lyrics it says

I was really expecting it.
I was really doubting it.
What was it? Who was it?
They say he's a good person.
He seems like a person I don't care about.

i thought that song was for her father because she said that he left and she doesnt care about him anymore and thats what the song kinda says in it and in some of the songs she would be looking for someone called her lover or true love and i didnt expect that to be family or friends and it might have been for Tomoya Nagase but in her songs she said she was looking for the one she lost and the one she truely loved and that makes no sence to me if she already has Tomoya Nagase??
