Why To Watch: The series offers a moral question to viewers: what happens when the guilty get off with no consequences? But instead of just focusing on the question, the series instead investigates it through dynamic characters who themselves are grappling with their own trauma, their views on the world, and making choices as to who deserves punishment and who can dish it out. The series also has a larger mystery that plays out fantastically, with Park Sung-woong acting as a powerful anchor that the story revolves around.

The way she has to break her body over and over again to not just be embedded in as a mole but to develop layers to her persona that hide her revenge makes this thrilling Kdrama series a must-watch. As a character, Ji-woo is a kind of resilient that is heartbreaking as much as you root for her.

At the center of the organization is Jung Gi-Cheul, a charismatic boss, a brutal fighter, and a man who has lost too much not to be at the top—and he knows Jun-mo’s wife.

2. Bargain

After a catastrophic earthquake, the victims, traffickers, and buyers are all trapped inside the crumbling building. Cut off from the outside world, they must fight to survive the aftermath at any cost.
Why To Watch: Shot all in one take, Bargain is a cinematic feat over the course of six episodes. The characters are stunning, the environment is dynamic, and the morality that is called into question is as gray as can be. Every piece of Bargain is fascinating, and it’s better left watched than explained.
1. Somebody
Synopsis: Kim Sum is a developer for the social connecting app “Somebody.” A lonely woman, her strength in engineering comes from the want to create companionship even though she has difficulty communicating with other people.

An attractive man with deep-running secrets, the murders are closer than anyone can see.
Why To Watch: An erotic thriller, Somebody is a masterclass in misdirection and manipulation. Many of the series’ moments are so extremely difficult to watch, but as they lead up to an epic finale, it all pays off with more than just shock. The dynamic between Kim Sum and Seung Yun-O (played by Kim Young-kwang and Kim Hae-lim) is electric and unnerving in the best way. Passion, revenge, disgust, and malice all combine in something truly thrilling.
