Shouldn't "増えてく" be translated as "increasing"(in number)?
The title should be "Foundation of a state in another world with a hand-built colony village : Carefree life on an uninhabitated island with an increasing number of brides" or something along these lines.
no eng pages yet? noticed that there's an indo version but years of reading translated Naruto on newspaper cheap-prints have made me kinda traumatized at reading indo-TLd manga
