Help me find the book of my dreams?

Ok I had a dream a while ago about a romance book I wanted to write in the dream about one character (character A) who had a million walls up and was really averse to being vulnerable and a love interest (character B) who was so patient and accepting and willing to wait for them and help them to be ready to open up and they just loved them enough to be there for as long as it takes for A to come to them……. But i can’t write so does anyone know of any romance books with a dynamic like that lol
