A week after Hiroshi's arrival, he discovered the first note tucked beneath his door. It was a hastily scrawled message on a torn piece of paper that read: "They are coming. Watch the moon." The message was peculiar, but Hiroshi brushed it off as a prank or the ramblings of a paranoid neighbor.

In the days that followed, Hiroshi found more notes, each more cryptic and ominous than the one before. They spoke of "the others" and "the event," but the most unsettling aspect was that these messages were dated from the future. The latest note read: "41 hours. Prepare for the shift. Trust no one."

The mysterious messages sparked Hiroshi's curiosity and creative energy.
