i think a novel's got well-written fem chars when instead of fanon ships you get a lot to talk about thru canon ie how hsy's role is defined in how kdj & yjh are both "novels" but hsy isn't & how that uniquely positions her against the hegemony of the story she's trying to fight
if kaizenix is relevant to hsy's character it's because of this: that she did turn herself into a story for kdj to read but she could only work within kaizenix's genre constraints and we see a direct thematic evolution with tls123 & epilogue hsy breaking past story limitations
this includes how alt hsy fixates on finding the author of WOS while having a specific image of who that's meant to be, trying to dissect author's psyche/motivs thru WOS's tragedy & apocalypse. then decides it doesn't matter WHO writes the damn novel so long as it's written &
can reach the reader. this challenges the fixity & authority of the "author" of a story and ties into Death of the Author where it's actually in the reader's mind that the story is actually being written, the reader is the generative field, and the text(or protag) is non existent
if the right reader doesn't exist to read it. and this is conveyed powerfully when hsy cries out in despair "what did i write this story for?!" not so much she failed at writing the story but because she knows it's not her who decides how the story ends but the reader
no matter what she writes, the ending's out of her hands/reach. and that will become her biggest tragedy in sidestory (speculation)
