Sense And Sensibility by Jane Austen
Elinor (the sense) and Edward love each other while Colonel Brandon loves Marianne (the sensibility). Since all of Elinor and Edward’s interactions happen before the novel opens, you have to take Elinor’s word for it. You certainly can’t go by Edward’s actions, since he is almost never around – and when he is, he is engaged to Lucy. Whenever Colonel Brandon visits the Dashwoods, he spends all his time with Elinor, not Marianne; and whenever Elinor speaks of Colonel Brandon it is with more fondness than she displays towards anyone else, including Edward. Yet somehow Elinor and Edward marry, and so do Marianne and Colonel Brandon. Didn’t see that coming.
When Mr. Dashwood dies, he leaves the bulk of his estate to his son by his first marriage, which leaves his second wife and three daughters (Elinor, Marianne, and Margaret) in straitened circumstances. They are taken in by a kindly cousin, but their lack of fortune affects the marriageability of both practical Elinor and romantic Marianne. When Elinor forms an attachment for the wealthy Edward Ferrars, his family disapproves and separates them. And though Mrs. Jennings tries to match the worthy (and rich) Colonel Brandon to her, Marianne finds the dashing and fiery Willoughby more to her taste. Both relationships are sorely tried. But this is a romance, and through the hardships and heartbreak, true love and a happy ending will find their way for both the sister who is all sense and the one who is all sensibility.
