The narration was ok for me except the very last bit, which seemed to squeeze too much exposition in a few moments, but otherwise the story was pretty straightforward. Sae reminds me of Rise Kujikawa with Mikuru Asahina's personality in many ways, but is a little too passive for my tastes. Nonetheless she does have potential so it's worth watching anyhow.
Her ending song reminds me of a Burt Bacharach tune from the 60's for some reason though...
