In both the dramas male and female lead met each oter in childhood. Female leads were rescued by the male leadd in childhood. Both the dramas give same vibes just arrangements and ages are different.

Both have genius but lack of social skills main characters (Though The Victims Game's MC has Asperger's syndrome while Stranger's MC became like that after undergoing a corrective surgery)
Both have intriguing crime and mystery story
Both have great writings that you can relate and sympathy for every characters
Both have male-female duos with great chemistry but no romance
Both have superb actors and actresses with really really great acting skills
I literally watched TVG after Stranger S2 and so pleasantly surprised with it, go watch it folks.

They're both great dramas
Both Historical
Battle of Changsha is a C Drama, while Queen Seon Duk is a K Drama
Battle of Changsha is more about war, while queen seonduk shows the life of a princess who had to run away.

Story wise they're not very similar, but they are both historical dramas.
Battle of Changsha shows more historical elements, while Scarlet heart is more emotional.
They're both dramas that will take you on a ride of emotions.
Although in scarlet heart there is no War; it shows the mistreatment the fourth prince faced and how he climbed his way to the throne

The over-all vibes of both shows are quite different, but if you're into supernatural beings who are also detectives, maybe check this one out.

Both deal with a police inhestigation to find a serial killer. The villain in both dramas are really twisted and seem unstoppable. The actors playing villain do an excellent job in both dramas.
The female lead in eaxh drama is bright and male lead is more reserved and introverted.
In TGWSS the female lead has a painful past wheread in Flower of evil it is the male lead who suffered in his past.
Overall both dramas are addicting. Flower of evil is more heavy and the other one is more light.

Coming of age story about 2 characters finding a relationship where they least expect it, and with who they least expected it.

dr. koto synopsis first few line remind me romantic dr. kim

It is a remake of this drama. Same story but much better CGI and acting. It is basically a much better quality version of this drama.

Eternal love of dream is also a fantasy story about the heavenly realm,demon realm and the mortal realm.Both the dramas have heavenly emperors.the idea of God is war( Mo Yuan in ELOD and chu xuanji in LAR)is also common.

Love, love, love this show. Like Love O2O the couple stay true to each other regardless of misunderstandings or other peoples interference. The female lead is also a lot animated than in Love O20. The male lead still has that inner strength/aloof persona but he mellows out as the show progresses. While the show is set in the gaming industry it doesn’t focus on the gaming side but the business end. This is the perfect anti-stress romantic drama. It is definitely on my repeatable list.

Very similar world with magic and dragons.

The main similarities are:

Male and Female Lead are singers.
ML unable to cultivate since childhood.
Met female lead when younger.
FL is saintess with great power, but seems aloof. (she's new to acting, however I'd say her performance is about the same as this FL)
Destiny and unlocking levels and great schools and tournaments with rankings.
Powerful evil clan, that provides conflict, but is defeated many times.

My Favorite

Male lead that has a (deep friendship/symbiotic relationship/Master and Servant like relationship) with a non-human female support.

I don't remember any kissing in this, but there is affection. The actors are new.

The bad boy image of the 4th prince in Moon Livers is similar to Qinyue. Both characters are dark and are competing against the “white knight” to win the heart of the girl.

Both dramas have the same leads as the main couple. Also both dramas have a contract relationship as part of the story theme.
