Tunnel (2017)

same feeling... guess while watching signal the writer of tunnel thought- wouldn't it be better if the cop came to the future himself rather than just talking through a walkie talkie.
almost similar dramas

1. Both are about crimes
2. Both have supernaturals in order to solve crimes
3. Both have good stories
4. both are at police station setting.

Both dramas have the same investigator and culprit in a cat and mouse chase. It gives that similar vibe for me.

The only difference is that Tunnel has a time travel element but Hello Monster does not, but deals with something in the past as well, but no time slip to complicate it than it already is.

Voice is a fantastic police drama. The same chanel that Tunnel.
If you like adrenaline and police mystery with much suspense, I indicate watch Voice.
You will like it from start to finish.

In 1986, Park Gwang Ho works as an excellent and enthusiastic detective. His life changes when he’s pursuing leads in a serial homicide case and then passes through a time portal, which transports him to present-day Seoul. He meets a new partner Kim Sun Jae, an elite detective who happens to be a bit eccentric, but is one highly skilled investigator. The detective duo will also find help in psychology professor, Shin Jae Yi.

The plot and setting is not exactly the same . But A Policeman Solving an old mystery with his new partner, who turns slowly from a distrusting acquaintance into a close friend -- feels same as Beyond Evil.

Personally, I really like Nine: Nine times Time Travel :D and after watching first episode of Tunnel, I am already addicted to it!~ Those who love time slip dramas will definitely love this too :) (if you aren't too picky) It brings me laughter (natural type of comedy), tears, nervousness etc. while being intense. While Nine:Nine times travel time travel via incenses, Tunnel is via Tunnel as the title mentioned.
Cases were interesting.

Almost the same story and the only difference is that the lead gets stuck in future(present day).
If you liked tunnel I’m sure you’re gonna like this one too.

Both dramas involve a person "traveling through time" in a way.
I'm not sure if Reunited Worlds has anything to do with time-traveling yet but it could.

Both shows deal with characters in different time lines affecting a case. In Tunnel, the ML travels from the past into the future. In Kairos the ML is in the future but can communicate via a phone with the FL who is one month in the past.

The protagonists go to the future because of a criminal's pursuit and can only return if they solve the case.

the plots aren't anything alike, but they're both exciting dramas. both quench the in-the-mood-for-a-crime-thriller-drama thirst.

- Both are about crimes
- Detectives try to catch a serial killer
- Both are in the police station set
- Blind has a lot of climaxes whereas tunnel revolves around a lot of mysteries

While pursuing a criminal, a detective is transported into the future. He has a hard time adapting to the future and wants to do things in his old way.

Both are time travel suspense thrillers. In God's Gift, the female lead goes back in time to save her daughter from being murdered and in Tunnel the male lead travels to the future to catch a criminal he wouldn't have been able to catch in his time.
