Mo shuttles through the world of reinforced concrete, but alone protects Lan in the small green house.
Lan's friends and relatives gradually left the little green house due to the changes of time, but Lan didn't have to, or even change her original intention, because Youmo was there.
And Mo, who was tired of the war, seemed to have found his own solace in his cabin.
The small green room under the reinforced concrete carries each other's memories and laughter, and it is already an oasis in the vast gray.
Purpose: People need to protect themselves and heal themselves.
