I wonder how many people from now will die of the infectious disease.
Still people in the world looks having some optimism that a day would come when the virus
disappears naturally or is conquerred with some vaccines or human-beings get to acquire the antibodies against
the virus. But, we, actually, don't surely know such convenience will occur.
The number of people might decrease gradually at first, accelerating the number of the death from the disease day by day,
and one day, we might have an ominous premonition of our human-beings' extinction.
Then, panics with anger and sorrow must happen everywhere. But, in the end, the day of our bing eradicated
must come. I haven't thought Dies irae is something like this.
