"Kys me," quod she, "we be no lenger wrothe,
For, by my trouthe, I wol be to yow bothe –
This is to seyn, ye, bothe fair and good.

– Geoffrey Chaucer

The Canterbury Tales, The Wife of Bath’s Tale. Because the Knight choose the right answer to the Loathly Lady’s question whether she should remain old and ugly or become young and beautiful, she rewards him. She asks him to kiss her, saying that she would be both beautiful and faithful to him.
