a poetic romance story

i need a romance story where the guy is obsessed with the girl, think the notebook vibes (yes it is cliche but i love it🥲) . in that movie he writes her so many letters and says the MOST poetic romantic things that no guy in this day and age would and i just need to get lost in a book like that that has very good writing. i don't have any other books to refer to because I'm trying to get into reading and I only can give an example of a movie I've watched
