The rain can't possibly keep falling forever, otherwise the Japanese would have died out ages ago.
After seeing the sun peek out for three days straight, Nozawa knew the Meiyu season was finally wrapping up. This was almost a whole week shorter than he expected—apparently, after five hundred years, the climate has changed a lot, even the Meiyu season has shortened by nearly 15%.
And once Mr. Sun started clocking in for work as usual, daytime temperatures began to soar. The rainwater accumulated during the Meiyu season started evaporating rapidly, and Central Japan officially entered the muggy, stifling peak of summer.
This was a bit of a nightmare. Nozawa was from the north, so he was naturally heat-intolerant, and humid heat was even more unbearable.
