Is there any anime where the male and female lead have been surviving in the wild?

They have experienced various difficulties and dangers in the wild. 2. Sword and Sword Arts: Kirito, Asuna, and the others experience various adventures and challenges in the wild. 3 " Gate of the Fate Stone ": The protagonists Okabe and Reiko are trapped in an experiment. They need to find a way to escape and survive in the wild for a while. 4." Full-time Hunters ": The main characters, Chiyako and Miyako, experience various adventures and challenges in the wild. 5 " Little Lin Family's Dragon Maid ": Kobayashi and the Kobayashi Family's Dragon Maid experienced various difficulties and challenges in the wild. These anime works all had plots of the male and female leads surviving in the wild, but the specific plot and style were slightly different.
