Suggest me a classic romance novel

I want something nice with a happily ever after. No crazy tragedies or unresolved heartbreak, just two people falling in love and being completely devoted to each other.

I’ve been exclusively reading depressing and despairing books for a long time. American Psycho, The Road, A Child Called It, Lolita, Flowers for Algernon, Night, are some I’ve read in the last year. Not to say they aren’t well written or the subject matter isn’t important- but I feel like I need to start reading happier, lighter stories for my own sake.
