The Flower Duet (Lakme)....?

Question

.... Can anybody recommend another short opera piece with the same haunting quality? Even though it sounds sad at some points, there are some beautiful notes that lift you up again. Thank you!

Answer 1

I can remember many.

It may sound "sad" at some points, but if you were to research the libretto, you'd find that there's (dramatically) no conflict in the duet.
