The Game: Towards Zero

Just like The Game, Signal deals about murder cases and supernatural occurrences that help investigation teams solve them. While Signal does this with a walkie-talkie that connects the present to the past, The Game deals about someone who can see the death of people. Both try to solve cases with their unique ability. Also both resolve around cases that shape each main character. the cases that shape them are quite similar to one another as well however due to spoilers i cannot go deeper into this.
Signal is a masterpiece of masterpieces, The Game seems to go into a similar direction with it as well.

Similar ability shared by the main protagonist.

- in both dramas the main leads have a a special gift (in the game: towards zero it's de male lead and in the girl who sees scents (pretty obvious) it's the female lead).
- both dramas revolve around a (psychopath) killer.
- in both dramas the main lead helps out the police with their gift to catch the killer.

while the girl who sees scents has more of a romcom feeling, the game: towards zero is more darker and is a melodrama.

- Male Leads helping the police
- Female Leads as cops
- Female Leads fathers have died because of a serial killer
- Copycat cases start to happen again
- The killer is someone they know (won't reveal how it's very similar cuz that'd be a spolier)

Bring It On, Ghost is another Supernatural/Fantasy themed drama staring Ok Taec Yeon. Instead of seeing peoples deaths he sees ghosts.

In both dramas the main leading characters have the power to see how a person dies. Both are thrillers where the main leads work together
