Based on a webtoon, the film "Karma" revolves around a fateful accident, connecting 6 characters in a story about a career of good people.
They are witnesses Beom Jun (Park Hae Soo), surgeon Ju Yeon (Shin Min Ah), debtor Lee Hee Joon, Gil Ryong (Kim Sung Kyun), successful doctor Lee Kwang Soo and Yu Jeong (Gong Seung Yeon).
After airing on April 4, "Nghien Duyen" quickly attracted attention because of its thrilling plot, overlapping relationships and unexpected twists.
The film opens with a fire, followed by the story of the debtor Jae Yeong - a man who lives with his old father and is chased by black society. If he did not pay within 30 days, Jae Yeong would be killed and his organs would be taken away and sold.
At the same time, Jae Yeong's father had an accident and had to be hospitalized. When he returned home to get his father's things, he found his insurance and decided to plan to hire Gil Ryong to kill his father to get 500 million won in insurance.
Meanwhile, at a remote resort in the mountains, a successful doctor is dating his girlfriend Yu Jeong. Due to an incident, the two had to leave at night.
Because he had drunk alcohol and had had had an excessive intimate act before, the doctor accidentally stabbed a person. Instead of reporting to the police, they decided to hide the body but were discovered by witness Beom Jun. To cover up, they gave him money and forced him to become an accomplice.
After this incident, the connection between the 6 characters gradually reopened.

"Dating Group" is 6 episodes long and each episode is told from the perspective of a different character.
In the first 2 episodes, the characters seem quite unfamiliar, seemingly unrelated. However, from episode 3, important details in the case were gradually revealed, and the audience began to notice the fate of the characters. But that is not a good relationship but a "fate".
That is the relationship between witness Beom Jun and Yu Jeong, Gil Ryong; the painful past of Ju Yeon and his debtor Jae Yeong; the mysterious appearance of Doctor Jun (Kim Nam Gil) - Ju Yeon's boyfriend and the boss of black society ( cho Jin Woong)...
Although it belongs to the mystery thriller genre and criminal psychology, "Nghien Duyen" is still entertaining and exciting for viewers. In particular, the warning "everyone reaped the fruit", greed leading to hell is emphasized in each episode.
This was also shared by director Lee Il Hyoung before. He wants viewers to gradually explore the knots, like untied a thread, instead of grasping them all at once.
In addition, the impressive acting of the cast helps the film become more suspenseful and dramatic.
In the film, Shin Min Ah appears with a rough face, somewhat confused because of insomnia and has always been haunted by past injuries. Although weak, her character is somewhat scary in some moments.
Along with that, Lee Hee Joon successfully recreated the role of a bad son, Park Hae Soo transformed into a selfish and hated man, while Lee Kwang Soo and Gong Seung Yeon also took on roles with strange colors for the first time.
