Are there any dramas that are the opposite of an Isekai, someone from a fantasy world coming to ours? Because those are my fave and their no reverse isekai tag.
There are quite a few that end that way with the fictional character coming to reality for a happy ending, but these are ones where the whole plot is that:
Please Don’t Spoil Me (the first two seasons FL goes into a novel, the last three has the ML coming to the real world from the book)
The Next Stop W (cdrama version of W, ML and FL go back and forth between the manga world and the real world, with the fictional ML often in the real one)
Dear Diary (maybe? ML comes from FL's diary to the real world but there is a twist that he's actually a real person who time traveled)
