W (2016)

Both dramas are about a ML who comes from another world (the past/a manga) to the modern world. In both the FL can influence/change events by writing or drawing them in a book/manga. Both couples have a list of romantic things the FL wants them to do. Both MLs begin to fade away, starting with their hands going transparent/able to pass through things. There is also a villain from the ML's world who ends up in the real/present world.

Space and time travel.
Romance.
Fantasy.
Trying to change the fate.
.........................................................

I felt Love Crossed had the vibe of W.
What happens in "W" is a girl gets into a comic world. She doesn't believe her eyes after getting a glimpse of the boy live. Similarly what happens in "Love crossed" a girl uses a game where she gets a virtual boyfriend and one day she somehow ends up entering a secret house where she finds the boy (her virtual bf look alike) who actually exists in real life.

In both, the ML is a manga character who enters the real world and the FL is a human from our world who has loved/been interested in the character since childhood.

similar story, W is korean drama, Game Breaker (Dream breaker) is Chinese remake Movie.
in both Male Leads are super hot, tall, handsome guys ))

"W " shows connection between cartoon world and real world
"Signal" shows connection between past and present world
both drama story is stop the crime or search for culprit

Both take place in different "worlds" - W has the real and the comic book world, and Will You Be There has the past and the future world.

Both are fantasy shows about romances between two people from different worlds who should have never met if not for a temporal shift in time and worlds. Both are fish out of water stories. Both sets of main characters have to figure out who is trying to kill them and how to survive all the attempts on their lives.

Both has unexplained phenom. Great couple chemistry. Very interesting story line.

- The Female Lead gets involved with a comics character : the Male Lead.

- She enters the comics world.

- They must face struggles toghether.

Same idea.

Seung Hee, after losing his girlfriend in a tragic accident, left for 3 years. When he came back, he sought to make a film in a rural area. Someone caught his eye - Bok Shil, who looks exactly like his deceased girlfriend, Hye Soo. Seung Hee followed Bok Shil in order to get some answers and ended up falling for her.
Still the questions remain, is he attracted to Bok Shil because of the memories of his ex-girlfriend, or does he like Bok Shil for who she is? What happens when competitors come into the picture and families opposing their love?

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.
