both have a loner main character that has a gift that is hard to deal with and doesn`t really want. the male lead is initially reluctant to help the police when they approach him. he does help eventually.

Both are military-themed. Even though they're quite different when it comes to the plot, D.P. is an excellent drama and I would highly recommend watching it.

The male lead in Tale of the Nine Tailed is also a character in Goblin. Besides that, both dramas have a supernatural storyline and i believe that anyone who enjoyed this drama will also enjoy Goblin

even if the storyline is not the same but king of qin( Eisei) mother is the FL in The legend of haolan. In TLOHL we get the see the romance of Eisei parent and the birth of eisei from a first son of hostage prince to crown prince of qin dynasty INTO king of qin.

In The king’s woman Eisei(yin Zheng) fall in love with the girl who he killed everyone in her kingdom they storylines here is very tragic we get to see the romance king of qin and his motive of wanting to unify China

The dynamics between a senior police officer and his young recruit are very similar, with his reluctance to have her in his unit, and the slow burn romance that follows, without it being the main focus of the show. Also, there is a lot of action in both dramas and the good guys are trying to catch the bad ones.

Queen of Mystery is about a frustrated profiler played by Choi Kang Hee who likes to tag along with a detective in solving crimes while Through The Darkness is about the beginning of Korea's profiling system. Each episode of both shows explain possible behavior of perpetrators and how crimes are committed.

Both shows live by the basic forensic (exchange) principle “Every contact leaves a trace” by E.Locard.

Both Korean dramas tell the story of friendship between 3 girls and their stories of romance & career. The ages of "20th Century Boy and Girl" main female characters were 35 years old. While "Thirty Nine" were aged 39 (obviously).

These 2 dramas both have a similarity, about 3 girls who were best friends, and their stories of their career, romance & friendship. "Thirty Nine" is a Korean drama whose characters were on the verge of becoming 40. While "Fabulous 30" is a Taiwanese drama whose characters were on the verge of becoming 30.
