History is an endless river, and a drop of water is a world. Countless causes and effects create countless possibilities, intertwining and converging into every drop of water in the river of history, guiding the direction of the river's flow.
The splash caused by a drop of water is faint, but if there are enough water droplets that have been changed in direction and converge into a stream, it may be possible to break through the gap in the weak point of the "dam" and find a tributary for "him" that escapes "inevitability".
