Kei×Yaku: Parceiros Perigosos (2022)

both mafia themed with a dark and gritty storyline. both have great production, chemistry, acting, casting and soundtrack

these two show are siblings! They start the same storyline, our police boy suspects other one about murder someone etc. Both show is bl/bromance with dark scent (Beyond evil is darkest of course)

Intrigue, thriller and two partners with different life worldviews team up to find out a truth about a shocking incident

Both feature characters from different profession but developed a camaraderie after finding out they have the same goal. Great chemistry of main leads, both have BL undertones/censored bromance. The only difference is that one is a happy ending and the other is a tragic one.

Both are action packed and slow paced w/the development of the characters. Artsy and Intriguing, as well as the plot in where the two protagonist help each other solve a crime :DD

Funny man Nick Cheung Ka Fai and heartthrob Louis Koo Tin Lok are teamed up by producer Wong Jing in action filled comedy film spun out from the gambling genre he helped to create. Internationally acclaimed director Tony Ching Siu-Tung does excellent job making Cheung and Koo look like highly skilled martial artists. Cheung plays a low rent gambler with a typically huge ego who seeks out a legendary gambler, played by Koo, who dropped out of sight several years earlier. Involvement of Japanese production funding and the casting of Yasuaki Kurata mandates that various Tokyo locations are used for international flavor while the various plot intrigues play out.

story is similar, two male characters fights for the justice. Two of the characters in the shows are different kinds of nature and humour. Both show is bl/bromance with comedy + dark scents

maybe not story but the vibe is similar, ther are two male main characters which fights for the justice, and only one of them is police. One character looks like carefree and other one is little serious. Both show is bl/bromance with comedy + dark scents also

Bad Guys is about gangster and mafia characters, and Kei x Yaku has a Yakuza protagonist. Both are damn good; I'm actually a little obsessed with Kei x Yaku not gonna lie!

I can't explain that but these two shows have similar vibe even though their plot is totally different, maybe the reason is they are both Japanese bromance/bl series with talented actors, or maybe emotinal parts/helping each other part catched me, i don't know but i highly recommend both series
