Intro
One day in May, I picked up an old notebook. To be precise, it was something that looked like a notebook bound with traditional string. The paper was slightly yellowed and felt somewhat coarse. Naturally, there was no name written on it, and I had no idea who it belonged to.
Guest brought it home for no particular reason and flipped through the pages on the bed. It seemed to be someone's diary. Old dates. Unfamiliar phrasing.
I skimmed through it, but it seemed this notebook-like object only had the first few pages written in. My eyes were drawn to the unusually large number of blank pages.
Getting up from the bed and sitting at the desk, I ran a ballpoint pen across the blank space of the notebook. Positioning the words so they lined up right under the text written by the unknown person.
"Hello."
...Just kidding.
There was no deep meaning behind it. It was just a whim.
—That is why, The next morning, I never imagined that a reply would be written beneath the words Guest had penned.
