O Jogo: Rumo à Zero Hora (2020)

From the first episodes it seems to be a Similar premise. Both are about a guy who "sees" things and a lady cop.

Both stories have the theme of seeing a part of someone's future (the bad premonitions/deaths), meeting a person who interrupts what's "normal" and "unchangeable" to them, and being able to change fate.

Both are dark mystery/crime dramas with a group of detectives trying to identify a sadistic serial killer. The same actor is the ML in both.

These two dramas comes off with a similar vibe, where both male leads possess a supernatural ability. In both dramas, the antagonists are ultimately after revenge and the male leads are trying to protect the female leads from involvement as they work together to solve murder cases. Both are thrillers with romance, neither contains comedy and both have mature acting where the female leads got a backbone.

In Sampat Ruttikan, she can see the death of every person she touches.
In The Game: Towards Zero, he can see the death of every person looking inot his eyes.

Both MLs have the ability to look at a person's eyes and see their death (in TGTZ he can see the exact way someone will die, in Aftermath he can only see that death is imminent). Both MLs use their ability to try to stop a serial killer.

ML has supernatural ability to see the future (and witnesses death) and tries to change it. Mystery/crime and romance elements. Same actor as ML.

ML has a supernatural ability. Mystery and romance elements with some darker moments. Happy endings.

Former serial killer Byung Soo gets diagnosed with Alzheimer's. The doctor tells him that it's due to the aftereffects from a traffic accident 17 years ago; the same accident that stopped him from his killings and allowed him to live a normal life with his dear daughter. So when a series of murders occur near his town, Byung Soo gets worried whether the killings are his doing during his memory lapses. But then he comes across Tae Ju and instinctively realizes that he is the serial killer. He reports this to the police, only to learn that Tae Joo is one. Byung Soo tries to find firm evidence that Tae Ju is a psychopath, but only raises Tae Ju's interest in him and his daughter. And now with his memory slipping, Byung Soo must find a way to protect his daughter from Tae Ju.

If you liked one, you will surely like the other!!

A boy’s father is falsely accused of a heinous crime and convicted. The enraged boy lives only to avenge his father’s wrongful conviction and harsh sentence. Through his actions, the son brings the truth to light, changing the lives of everyone who crosses his path for better or worse.

The personalities and actions of the sons in each series are diametrically opposed as well as the outcomes. One is twisted by his experience and being abandoned by his mother while the other embodies the goodness ingrained in him by his father. The two dramas provide a fascinating look at how two different people can have nearly identical experiences and react to them quite differently.

These both have a 'serial killer' living like normal innocent people. The basement is too familiar to me when I watched Flower of Evil.

The Male lead can see a person's moments right before they die, and he also thinks it's unalterable until the Female lead proves she can change one's fate. Both are also related to each other in some way (past and future).

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.
