Favorite Black and White Yaoi's

A foreigner from a primitive tribe comes to japan as an exhange student (university) so he can learn of Japanese culture and overall society in the modern age. His host is the Uke, he teaches him the language and everyday stuff as well. they fall inlove and the Seme takes him back to his tribe to meet his people. The uke ends up staying and opening a school to teach the kids. This was so good. The smut, the story, the characters!
