Modern day woman ends up in novel.
Mini series with a novelist end up in a book and falling in love.Whiles trying to return home.

A modernw day woman travelw back in time via accident and meets her cole face husband who has a childhood lover.

Along the lines of being from another time and going back and being an odd one.
The female lead seems to have various reasons to be around the male lead even after come from another time still falls for the male lead from this time line.
So I think they are similar in that stances.
