I'm looking for a manga telling the story of a woman who travelled from a distant land to marry a man from a different tribe. I don't recall their names; but the man is 12–15 years old and the woman is older. The setting is medieval-like. The artwork is very detailed, especially the clothing.
A few chapters later the people from the woman's tribe want to take her back because they didn't get any benefit from them.
The woman knows how to shoot a bow and arrow, how to knit clothes, and is good at hunting with bow and arrow while riding horseback.
