First I loved your brother, and now I kiss your feet in devotion; crown me as your sovereign, my darling, for I am your hereditary lover.

There is a delightful, cheeky wit at play here, where the speaker approaches love with charming audacity. By claiming they once adored the beloved's brother and are now bowing at the beloved's feet, they playfully frame their affection as an inherited, ancestral loyalty to the entire household. It turns devotion into a teasing, lighthearted argument—asking to be crowned sovereign of their heart because loving this family is practically their heritage.
