The Chaser

Both have a main character trying to reveal the truth behind someone's death ( in chaser it's his daughter and ghost bestfriend/ many more) both has powerful villains and you hold your breath during the whole drama.

While Two Weeks is about saving the hero's daughter in The Chaser the hero wants to take revenge for his daughter. Both dramas are emotionally very intense and both heroes end up being on the run and fighting against powerful people.

Both dramas are gritty, high-stakes thrillers driven by personal tragedy and the quest for justice, where the protagonists are pushed into extreme circumstances by events beyond their control — in Green Rose, Lee Jung-hyun is framed for murder, presumed dead, and fights to clear his name and uncover the truth, and in The Chaser, Detective Baek Hong-suk’s life is destroyed when his daughter’s death is revealed to be part of a political conspiracy, turning him into a relentless pursuer of the corrupt official responsible — each series features tense action, emotional depth, moral ambiguity, and intense confrontations within a dark, unforgiving world where powerful enemies manipulate the system against the heroes.

Writen by the same screenwriter, Park Kyung-soo, both dramas involves a corrupt political setting in the best way.

From the same writer. Both are intense drama that deals with a fight for justice against people on higher-ups(politics,judiciary,business). These drama shows how can a powerful person can bend and control law for their own welfare. And how a person can be blinded by money that leads to betrayals.
