W (2016)

They are both about women who fall in love with a comic book character that is able to come to life.

- the female lead also enters a different world (not a game)
- the male lead falls for the female lead

In this drama series, the female lead enters a comic book/alternative reality to save the male lead. It is quite gripping and well-made. You can watch it on Netflix.

Story characters come to life. Romance as well. W is more suspenseful than dear diary. Both female leads are confused the the beginning.
