What are some good slow burn romances that have no spice?

Hello everyone! I really love to read romance books but I am having a really hard time finding great romances that have no spoce in them. I already read the entire Anne of Green Gables series, Pride and Prejudice (and the beginning of Sense and Sensibility, although I am not a huge fan of how the story itself progresses so slowly), Wings of Starlight and a couple others. I am not a huge fan of enemies to lovers and I absolutely DESPISE spicy books. It is uncomfortable to read and goes against my beliefs, so I am looking for 0 spice. Also, I love slow burn books!

Sorry for the long text, I'm just trying to vary from tragedies and criminal romances for a while 🫠
