The King in Love (2017)

Both take place in Goryeo and have a love story. Hong Jong Hyun plays a main charater in both. In SHR, he plays an evil brother plotting to take the throne. TKL, he plays Crown Prince's best friend. The locations in both shows are extremely beautiful. Lee Joon Gi and Siwan's characters fall in love with the female leads who care for them. Lee Ji Eun (IU) and Yoona's characters go through many hardships.

Lee Heon is the king of Joseon. 7 years ago, when he was a crown prince, his beloved wife died. To this day, he has not been able to get over her death. For the past 7 years, the royal family and government members have tried to get King Lee Heon remarried without success. The nation has also implemented a geumhonryung edict, which is a ban on all single women marrying during this time when the king has not married. People are furious over the marriage ban. One day, King Lee Heon hears of a woman named Ye So Rang, who claims the spirit of the king's late wife exists within the royal palace. Meanwhile, Ye So Rang is a swindler and claims to interpret marital harmony signs. She is arrested and jailed where Officer Lee Shin Won works. To get out of her predicament, she pretends to be possessed by a spirit in front of Lee Shin Won. During her ruse, she mentions that the spirit of King Lee Heon's late wife exists within the royal palace. She is then brought in front of the king and he asks her if she can really see his late wife's spirit. To survive, Ye So Rang acts like her body is possessed by the king's late wife. Ye So Rang's lies get bigger and more audacious.

not so similar, both are very good and quite unique dramas, hard to recommend something very similar, but both:
*about good friendship and same time love triangle between friends.
*both dramas have rare unpredictable love triangle, when you can't guess who will FL choose. Also, for viewer both guys are likable, even though we always choose one and ship FL with him, in these dramas, you will like/love/understand other guy too.
*period dramas (one historical, Goryeo period, second 80s),
*quite positive feel and nice watch.
*very beautiful cinematography.

not so similar, but both have:
*love triangle, unpredictable who will FL choose. For viewer both guys are likable, of course you will ship FL with one (you like) but you will like/love/understand other guy too.
*good historical + romance dramas.
*ML and SML are/become friends,
*quite good side characters and interesting plot (other then romance).

both are really good dramas, not just "one more historical romance", in "Chuno" fight scenes are best I have ever seen, also very unusual charismatic ML, in "King in love" is very good bromance and romance!

both:
*Historical
*very good bromances
*friends love same woman
*ML and SML at some point become rivals (especially in WBDS) but stay friends and love each other till the end
*you will have second male syndrome in both dramas, in TKIL he is very nice very good and loyal lovable guy, in WBDS he is anti hero super charismatic dark guy, star of the show. Both have sadness in their eyes...

Romance is very good in King in Love, and unpredictable love triangle, but in Warrior it is weak part, but bromance and SML is so good... both must watch dramas!

It is believed that when a person dies, their soul spends 49 days in Jungcheon, or Purgatory before their eternal fate is decided - heaven, hell or rebirth. That's where accomplished demon hunter Yi Kwak finds himself as he lies on the edge of death in our world. Blessed with astounding swordsmanship and the uncanny ability to see the evil spirits invisible to most, Yi enlisted with the royal squad of elite demon exterminators, the Chuhyongdae, following his fiancee's tragic death. In Jungcheon, he finds Yon Hwa again, but she does not recognize him - she is a spirit of the afterlife now, severed from earthly memories. Moreover, she is deeply entangled in a great war between the white-clad warriors of reincarnation and a swarm of dark spirits determined to forever shatter the cycle of life and death. The battle is desperately close to a terrifying conclusion, so Yi must draw his sword to defend the woman he loves and all they hold dear - and confront the same soul that was once like a father to him.

Both historical dramas with a similar romance dynamic and characters involved. Both are a good watch if you enjoy the more indirect and rather angsty type of romances.

Episodic saga from the first half of the 20th century follows Hero Hua from an ill-omened June day in his youth to a showdown 17 years later with a disaffected member of his martial-arts school, a Japanese named Invincible.

859 AD. The once-great Tang Dynasty is now declining. Numerous rebel groups have formed, the largest of which is the House of Flying Daggers, based in Feng Tian county. They steal from the rich and give to the poor, gaining the support of people. The local deputies have managed to kill their former leader, but the rebel group only becomes stronger, due to a mysterious new one. Jin and Liu, two police captains, are ordered to kill the new leader within ten days.

Both shows are about a complicated love story that includes betrayal. Both dramas depend on dialogues and indirect portrayals of love, such as stares and offering help, to progress the story.
