Connection

The storyline and directing was excellent. This drama captures end to end thriller and has surprising elements until the very end. It starts off with a good speed - gets you addicted to the series! I couldn't stop watching it, everything about this drama was just about great.

The casting was excellent too. Every role is assigned to proper actor/actresses. Everyone nailed their part, especially the main lead, Ji Sung. The addicted detective role was superbly fulfilled by Ji Sung.

This drama is filled with twists and turns, betrayals and backstabbing. It was a great watch, and it certainly deserves more rating than it has here now. 10/10 personal rating and 100% recommended.

Complete perfect series ever ...ji sung is the best korean actor and his choices are always extremely important and entertaining 👏 and in my opinion he is the k-dramas king for all his series until now.... It is just start but iam sure it's going to be the most popular and exciting one ....the dealing with crime and drugs is such an interesting picture to solve the solution of his friend's death.. The choosing of all cast is very good and everyone is perfectly playing his role , the pictures and locations are perfect ...... Iam just disappointed that two only episodes every week are announced 😕

It's another masterpiece of Ji Sung ssi. It has a great plot and all the actors are very good. Especially actor Ji Sung's drug-addicted acting makes the me exhausted.

From first ep and go on, the rate of the film did not slow down, and the desire to continue watching could not be stopped until the end. 14 episode is not enough for me. If it's possible I want to get season 2.

I would definitely recommend watching this great drama. The drama carried the curiosity with some unexpected twists buried in it.

And the characters in it also feel very close to the real world especially Jan Mido's cha.

This show is too good. Really good story. I don't remember any plot holes.

I was not sure if I should watch it since the rating is not that good, 7.9 at the moment. However, for some reason I felt I should give it a try, and it was totally worth it.

I liked the characters and the story. Until the last moment you are not really sure what happened.

Not much violence, some fights, some drugs, but I'm not sure if it is even moderate, maybe just mild.

I really like the interpretation of the main character, it seemed really good. I prefer this show than Stranger, which has a better rating. This one is far better.

The story revolves around a group of friends connected by shady dealings. The main character, a narcotics officer, is kidnapped and made addicted to drugs - a fact he keeps secret in order to investigate the supposed suicide of a friend.

The plot and dialogues are cleverly crafted, the acting is excellent, and the drama unfolds without any romantic distractions.

Nevertheless, there are some disruptive elements, such as prominent product placement or implausible handling of evidence within the department. Also, the way withdrawal symptoms are depicted is illogical. Probably they were crafted this way for dramaturgical effect or to depict the immense willpower of the affected person. However, it rubbed me the wrong way.

If you can look past these shortcomings (among others), you'll be rewarded by a captivating, gripping and entertaining show that never gets boring.
