Heck, the story may not even be in her journal, only the beginning and ending bit my have been in her journal, just different pages of her thoughts. When she says "Fleeting dreams fade into the distance, and all that is left now is me and my memories"
implies to me that she's thinking of Zeal.
Ofcourse, if this is Kid writing it, then its about her dreams of Serge, but it'd be weird that she has nothing left, except for her memories, when it's Schala who has nothing left.
I'd really like to see the japanese raw journal passage translated.
