Cruel City (2013)

Both dramas are involving police undercover. How the undercover cops fight the the dark world to survive and gain trust while not forgetting their morals and beliefs of justice. Both stories are filled with action scenes and carefully plotted and executed plans. Truly exciting to watch! The main characters are somewhat similar in terms of personality, filled with dark past, sadness, and rage but cannot show any of that to anyone.

In both dramas, the female lead receives very quick training before starting her job as an undercover agent in the drug world. She forms a strong friendship with another woman during her mission.

Similar plots, kinda. They both take place in shady environments that are difficult to escape from. A crazy good plot, and super suspenful, like save me.

All In is a classic mafia drama starring Lee Byung Hun, Ji Sung, and Song Hye Kyo. Both have action, intrigue, and romance. All In has a wonderful, surprising, and unpredictable ending. It's overlooked and underrated because it's older.

When you watch these dramas you should know you are in for a
Cruel ride
Painful romance
Rough life
Great music that digs deeper into your wound

So prepare your hearts

It's a drama but has the same noir feel and darkness. The leads have amazing bromance and their chemistry was outstanding.

The storyline revolves around drugs and drug syndicates.
Action scenes are present. Pretty brutal.
The leads go through different emotions

The two dramas are about undercover police work in the drug world. In both dramas a woman the main character loves gets killed and the main character goes undercover to find her murderer.

if you like action, darkness, and lead actors living in misery u will love them both. Jang Hyuk in iris2 n jung kyung ho in CC both did great in acting. Romance in iris 2 is stronger than cruel city.

Both about the underworld. While they're both thrillers, Cruel City has a noir flavor.

Although these dramas have different topics I saw someting similar. I believe you might like it. Just give it a shot...

When it comes to story and genre, they are nothing alike. But if you consider the nature of pain the characters go through; the pain they had to endure for years, the nature of relationships they have; the distance and the closure, they are similar. Both pained and hurt. Both dramas have a sad vibe and tone to them. Also, both leads had a noona figure beside them and coincidently they both did similar work, so they reminded me of each other. Female leads are also similar, the smiling, innocent, but hurt type.

Plus, both dramas are amazing!!

It has a similar vibe. It depicts a same kind feeling of helplessness even if its roots are different. Their soundtracks are a work of art. Less than evil may focus its attention on the policeforce and its flaws while Cruel City shows the people living on the other side of the law.

These two shows are not the same, but they both give me the same vibe. Both lead actors are amazing, and in both shows I was kept guessing about who the good guys were and who to trust (while knowing I was going to love the MC regardless of if they were good or not.)

Both dramas are pretty intense and each ep has a cliff hanger at the end of each episode. They also also both very well written dramas with amazing actors.
