Anime about fictional characters coming to 'real life'

Hey guys! Are there any anime/manga that have the trope of a fictional character within the anime coming to the 'real world?' Like within the anime there is a popular show or book and the main character's favorite chracter comes to life kinda thing. Kinda like the korean drama W. Preferably a story that has romance or fantasy, but any genre is fine!

Thanks in advance!! 😋
