Greek/Roman/Barbarian style era
Male is a king or emperor of the time, who of course is a woman's man. Until he meets the female character, of course he'll fall for her but is still staunch and dominant over his kingdom. He will become protective of her and care for her and though she is a slave/servant she would become his queen and wife and mother of his children.
She'll start off as a slave given to the king/emperor as a gift or prize, or a servant in his home. She's not that outgoing and she's quiet, she is taunted by other women and his guards and knights/warriors. She will fall for him when she sees the true soft kind himself.
