Whisper 

Whisper is a corruption-focused K-drama where a set of characters use various ruthless methods to reach their goals; the good guys want to uncover murder & corruption, while the bad guys individually seek to avoid trouble. There's occasional shifting alliances, but it's usually the two leads against everybody else.

The rapid pace of twists and turns keeps you on your toes, and the 'competent protagonist' is sure neat, though ultimately he's mostly the female lead's stooge throughout the majority of episodes. There's little he does that's not done to help her.

Sadly half of the time it looks like a cheap soap opera because of the way it was filmed - maybe it's mostly the framerate that has that effect. The camera work itself is occasionally obviously bad & even comical. I've watched some 25 Asian drama shows, and none had me laugh at the overdone zooms, silly angles, or poor cuts this often.

As many other viewers have noticed, you have to be able to stand "convenient" plot points, like how characters receive every phone call with millisecond precision to affect conversations they're having (and there's hundreds of these phone calls).

*SPOILER*: Several hours of plot development or rather lack thereof from the middle could be cut out because the end of Ep 11 renders them void. I found that really cheap and underwhelming.
