A lush daily life where humans and nature coexist.

A typhoon? An earthquake?
No.
Those are merely natural phenomena or risk factors in themselves.
American sociologist Charles E. Fritz defined a catastrophe like this:
In other words, a catastrophe does not exist simply because danger is present. It only becomes a catastrophe when that danger brings down society.
...
Then, conversely.
If a new social structure is built after the disaster, essential functions are restored, and everyone has returned to their daily lives.
If so, then this story is just a peaceful daily life.
Plants grew by swallowing everything living. Cutting them or burning them was useless. Roots sprouted again from where they were severed, and cities disappeared one by one under the vines. Humanity gave this event a name.

Once, it was certainly a catastrophe.
…
But humanity did not collapse.

The survivors built the final city upon the ruins.
Behind this miraculous reconstruction, there was a very special existence.

By 'offering' just one Affinity, the plants in that area feel a satiety equivalent to devouring thousands of humans and remain quiet for a long time. Sated plants are no longer the enemy of mankind.
That is how the city works. Humanity gave up Affinities, and in return, the plants gave up everything humanity needed to survive. Food, medicine, resources—everything is permitted.

Now, the Greening is not a catastrophe.
Ding-dong—
The doorbell rang early in the morning.
Upon opening the door, the first thing that caught my eye were a few pieces of plump, golden fruit.
Good morning, Guest.
Gaon smiled, his eyes crinkling slightly as he held the bag with both hands.
He is the neighbor living right next door and a civil servant working for the Verdant City's Ecological Management Department. He often stops by to share food or nice tea whenever he comes across some.
These were harvested from the management zone this morning. I thought it might be too much for me to eat alone.
The surface of the fruit was smooth and yellow as if it had soaked up the sunlight, and a sweet fragrance wafted into the entryway.
Just then, the front door of the house across the hall swung open roughly.
Giving things away again this early in the morning?
Noeul, her long, messy hair tied up loosely, leaned against the doorframe and looked Gaon over.
She is a guard who settled here from outside the city a few months ago and is now the neighbor living across the hall.
Gaon held out a piece of fruit to her without hesitation.
Would you like one too, Noeul?
