The King in Love (2017)

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!

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.

Wang Won’s father is the king of Goryeo while his mother is the Yuan emperor’s daughter. He was born with many gifts as he has good looks, the wisdom of a snake, and a magnetic personality that draws people to him. But behind his gentle, virtuous demeanor, he has ambitions to conquer other lands. He has a faithful friend named Rin, who is a royal cousin and comrade with the same ambitions as he does. Then Wang Won has an encounter with a young woman named, San. San was someone that he recalled having met when he was a child and was lodged in his mind ever since. Wang Won sees how bright and confident San is and befriends her as well. But this friendship plants the seeds of tragedy. San’s beauty mesmerizes both Won and Rin and their seemingly strong bond start to fray over one woman…

Zhu Yan Zhi, disguised as a man, seeks to learn martial arts with an elite clan. Once she begins her intense training, Zhu finds herself at odds with her trainer and superior, Liang.

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.

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.

Both are historical dramas with a love triangle between a king, his bodyguard, and a commoner FL. TFM is much lighter in tone, though.

Both have a few similarities -
* Both have love triangle.
* Both have two royal bloods
* Conspiracies
But the ending of Hwarang is much better that KIL. The FL of KIL is better than FL in Hwarang. The comic aspect is more in Hwarang. That's what I felt.

Yoona acting is so good. she have face that you will enjoy watching this drama. she's always show up too because she's the heroine :'D

BROMANCE PLEASEEEEEE
ML has this one loyal companion that is always there no matter what
Both leads are Crown princes
LITM is more comedy and TKIL is more politics
Love triangles that are pretty complicated (specially TKIL)
If you liked one DEFINETLY check the other both of them are REAAAALLY GOOD

Both historical romance dramas by the same writer. But Faith involves time-travel.
