In the lovely days of April, cherry blossoms drifted through the air.
A rising breeze, a sudden downhill slope, and a white beret dancing in the bright sunlight.
Have these things ever brought something to mind?
But suppose, on top of all that, a subtle change occurred in one part of the world's timeline. Suppose the boy on the bicycle no longer wore thick glasses, but instead had a pair of gloomy, lifeless eyes. And in that very same scene, the pure white beret still danced in the wind.
Then suppose that old bicycle mercilessly left a clear tire mark across the beret.
...And so the story began.
