Até Que a Morte nos Separe (2017)

Historical bromance drama set in the same era. A lot of espionage and deception. Rich guy asked their childhood friend to stay in their mansion. Childhood friend is a spy. And it involves the Japanese occupation.

Male leads with opposite characteristics that complement each other.
Both shows have great chemistry between the male leads as well as being able to show a soft and gentle friendship that is more romance than bromance.
The acting choices feel a bit similar too.
Good storylines that are intriguing and related to politics, murder and corruption.
Great set designs and costumes.
'Till Death Tear Us Apart' has more interesting side characters but a shorter run time (and is better appreciated after watching 'Love is More Than a Word').
The storyline of 'Killer And Healer' is more fleshed out while being a bit more common.

It just that the story, the set-up, and even the bromance reminds me of each other, just that if you want something short and full blown bromance then go watch Till Death Tear Us Apart..

It's sort of a prequel-sequel thing with basically the same prime cast.
