The most epic, yearning filled love stories??

Looking for your recs for the most epic, heart-twisting love stories. If you’ve heard the song “Would You Fall In Love With Me Again” from Epic, specifically the part at the end where Penelope sings “I would fall in love with you over and over again, I don’t care how where or when” and there’s so much yearning in it, that’s what I’m thinking of. I’d like it to be M rated, but it’s not a must. Obviously I’ve read Manacled, and breath mints/battle scars and many of the other OGs. Haven’t read Secrets and Masks, the auction, or the rights and wrongs series. Would any of these fit the vibes I’m looking for?
