In manga aren't click bait titles, but because there are so many published, you pick basically a title that explains the premise, otherwise it's harder to get users to read your manga. I suppose that also could work with novels, I'm not a book person, but I suppose you read a review or watched some video that recommended you a book, and if the title is self descriptive, then would easier to go to the book store and buy something that might is your liking.
It's common for romance novel titles to include the major tropes, e.g. The Scandal of the Duke’s Secret Baby. Here are some example titles from the Amazon Top 100(https://www.amazon.com/Best-Sellers-Kindle-Store-Romance/zgb...).
