I'm too lazy to translate the whole thing, but here's the gist of it:
Ch4: the manager found him and dragged him back. He came back with her because she said people were worried about him. Half a year later, he got a lot of media attention after he got back and he told them he survived the jungle without help (so that people won't try and look for the nudist tribe). Thanks to that, he got more jobs and gained fame.
On page 12, his stalker molested him and Lodi came :D
Turns out, after Michiru was gone, Lodi went looking for him in other tribes. He didn't know what country Michiru was from. He met this professor from England who asked Lodi to come with him to England and he agreed. 5 months later, he was introduced to the professor's Japanese friend, who told Lodi that Michiru is a Japanese name and found him on the web. Lodi learned Japanese in one month and came to Japan. They have hot butt sex :P Michiru found that the reason Lodi didn't do anal was because the nube tribe didn't know what it was.
Michiru decided to go back to the nube tribe, and they taught everyone there how to have anal sex.
Ch5: Michiru has gotten used to life in the nude tribe. The other couple was Riina (uke) and Rezai (seme). Lodi and Michiru started a new kink in the village when they had sex with clothes on and that's what the whole sex scene is about. Same with the bed sex at the end.
Sob* English part is great and so is the raw but I can't understand the RAW!!! So I'm sad.....
