Hi I'm looking for a romance between a white haired princess of a tribe who got married so her tribe would have access to magical stones I think. She got married to a black haired Duke I think.
dk abt the magic stones stuff but maybe this?: https://www.mangago.me/read-manga/forget_about_my_husband_i_d_rather_go_make_money/
I really don't like where this mangamis going. I mean he's saying no. Basically forcing that slime on him
