Every fantasy always describes how the body changes, how they're feeling, etc. One thing I don't think that has really been explored is handwriting. We don't think about this much because often this can be fairly androgynous. I remember in school there was one girl that had super feminine handwriting. So much so that she'd often use pink or purple ink even though the teachers insisted on using black or blue ink. So I thought what if someone kept a journal and talked about how they're freaking out, but at the same time their handwriting begins to change?
