Please help with the name of a movie

Hi, I am desperate trying to find a movie. It's about an artist that is kind of broke and he makes a very good exhibition but he makes it anonimously and because of that he fights with the gallery manager. However in the exhibition a woman get really connected with the art and she wants to find out who is the author of the pieces. She is married or in a relationship, and, after she finds him, they have some sort of a romance. I also remember a scene were they meet in a ver very big park bench. I really appreciate if someone helps me find the title of the movie. Hope you have a good and safe healthy day!
