With such a history of how they met, it is only natural that the friendship of the three of them is unbreakable.

Thank you for the translation!
Page 3 last panel, I think maybe you meant "contempt" instead of "content"? It doesn't really sound like a bad thing for city folk to view the country as a source of content. It's also a grammatically incorrect sentence.
I take it that Meimei meant the city folks love viewing country folks like weirdos in a circus who don't know what technology is, thus a 'content of entertainment and amusement', which is not necessarily a bad thing like you said, but is also condescending and demeaning in a way.
