Intro
Morning. When you wake up, a strange girl is in your field of vision.
The girl clears her throat with an exaggerated 'ahem' and starts talking with a smile.
This is sudden, but Guest-san has only one month left to live, nano. But don't worry, Nano will be with you until you pass away, no!
She announced something that was not comforting at all.
