Trigger

Thriller, Crime, Drama
The same actor, the roles are quite similar! Attack groups! Criminal Organization! Action!

Both dramas involve lots of gunfights (and some knife fights so far). Both MLs are retired soldiers (or mercenaries) and they didn't forget their training. Both dramas involve sidekicks who aren't what they seem to be.

Pretty good action, overall. Some interesting character portrayal, too. Recc'ed!

they both have two male leads who bond but later realise they have opposite goals.
i think both male leads in both dramas truly cared for each other and empathised on a certain level but couldn’t go against their own beliefs.

Both offer a mix of intense action, intricate plots, and compelling characters that fans of "Trigger" might appreciate.

The main characters share a muted personality, introverted, calm and being level-headed speakers. Their emotions do not show on their face unless facing extremities.
Trigger is a Psychological Thriller whilst Prison Playbook is in the Comedy and Crime genre, albeit a contrast in seriousness, the main characters share the same personality type.

If you want to watch something less serious in tone but still set in a crime-genre and has the same nonchalant introverted MC then Prison Playbook is a good reccomendation.

The same goes vice versa, If you want something more serious, more action and psychological manipulation with the same nonchalant introverted MC then Trigger is a good reccomendation!

Both shows show a case of an individual loosing their mind living at a Goshiwon (Residency). In Trigger, this only applies to the first criminal case in the show (roughly 2-3 episodes), whilst Strangers from Hell delves into this storyline as a whole.

During this time, both MCs in that case share the same values, emotional outbursts and mental instability. Both MCs have an influencing figure grooming them into commiting criminal acts.

Both shows tackle the subject of preventing or succumbing of these sociopathic tendencies to kill others. Trigger focuses more on the preventing side whilst Strangers of Hell focuses on succuming to that nature. Both shows are quite alike, crime, thriller and psychological. Two sides of the same coin.

Kim Hae Il (0r father Michael) is like alter ego of Lee Do from Trigger.
In addition he is played by the same actor.

The Killing Vote and Trigger share similar pretenses: involving the public, giving them a choice, and the resultant of deaths. Both MCs are Police Officers who do things in unconventional ways, and the enemy is closer than what they think. Both shows delve into the morality of taking justice into their own hands instead of relying on the law. Both shows have an emotionally driven plot, which makes them quite similar. For a more level-headed, calculative but risk-taking MC: Trigger is perfect. For a more impulsive, emotional and risk-taking MC: The Killing Vote is my rec!

Both shows are about pressure for societal change, urged on through violence on the wings of journalism that is morally dubious to say the least. Both shows have themes of revenge and justice and are fast paced.

Both dramas involve a lot of action and some vigilante justice. There are knives and good action scenes involving them, and also a lot of mobsters doing their thing.

Pretty interesting MCs in both stories.

It's also a criminal story, there are several gangs, but instead of drug trafficking, there's gun sales. The atmosphere is very similar! In both series, Kim Young Kwang!
