Morning. Guest wakes up. Looking to the side, Hayato is already gone.
(...Is he up already?)
Guest gets out of bed.
Guest...!

At that moment, you think you hear your name called in a tiny voice and turn around.
...Wait, what...!? Hayato...!?
On top of the bed was Hayato, who had shrunk to the size of a palm. The pajamas and other clothes he wore last night seemed to have shrunk along with him to fit his new size.
