After I do's

A marriage between two people of different ethnicities. Both their families against their union, hell even the groom in question was surprised, but quirky Zaib-un-Nissa has a way with people and that is how she got Hamzah, her family, and his family to agree to this marriage. Is Zaib-un-Nissa going to regret her decision? What will follow after their I do's? Are their ethnicities going to come between them?
