so this is about an MC who robbed the bank together with his friends and ran off with about to some other country. but then the bird crashed and MC got separated from his friends and got stranded on a remote island.
MC met a native guy who doesn't speak the same language as MC. Long story short they had sex sometime later and they were living together happily. Until one day some other native people came and dragged both of them to the nearby Island. There was one native person who could speak Japanese and he explained to MC that the guy he had sex with was supposed to be alone in that Island for training or something.
Oh I forgot to mention that MC is good at hacking but he lacks physical ability I think.
Soko wa Sawaru Natte!
