The three survivors of the doomsday were assigned by the base to go out for activities. They were assigned to their former orphanage. The three of them had a sudden idea that they did not want to return to the shelter. The three of them, who were familiar with the terrain, bypassed the group and climbed up the mountain behind the orphanage. Later, they found a hut on the back mountain. This hut seemed to be the accommodation of the former mountain guard. The wooden furniture was still well preserved and the walls were intact. The map and diary on the bed looked like they were about to fall off, the telescope by the window, and the stove by the bed. Everything seemed so calm and peaceful. It was so different from the current time when corpses were everywhere and wars were raging. Three girls who seemed to have never truly enjoyed happiness fell into despair. At night, the three tired and hungry people lay down in the dilapidated hut and fell asleep in their clothes. I don't know how long it took, but when lightning struck, the three of them woke up and found that they were no longer in the dilapidated hut. The three of them were reborn and lived a new life. I don't know what kind of life the three of them could live.
