Similar genre and storyline, set on the almost same era of time. Related to pre war time and very similar love story.

Both Male Leads take a pill (drug) that enhances their abilities...
Vivid Romance is about a guy who’s struggling with his police exam, and take a pill in a human drug testing place, has no side effects and become really smart and fit.
Bad papa is similar in the way that the male lead also take a human drug test and has no side effects from the pill but instead of becoming smart he come strong.

Reply me 1988 is my all time favorite drama. I almost got the same vibe after watching le coup de foudre. Both are wonderful dramas. Both starts with present life where the leads are husband and wife talking about their youth and how they have come to this point but the only difference is we don't know at first who the husband is in case of reply 1988. Both have multiple couples with wonderful stories of their own including their parents love.Both teach us to appreciate our families and friends. No annoying side characters which is a big plus point for any drama. Some might find both series a little slow paced but trust me its all worth it. So if u like slice of life dramas i would recommend both of them.Trust me they are very feel good dramas!! Enjoy

Written by the same screenwriters, they are really different. This is more a political drama about the Hangul invention. But in the first 3 episodes you can find Song Joong Ki as Young Lee Do (Great King Sejong).

Written by the same screenwriters <3 Arthdal can obviously put before Silla time.
Both talks about a cursed child grown up far away from their land. They both return to find who they are... in Arthdan also to save someone.

Written by the same screenwriters <3 Arthdal talks about the legend of a land, while Six is about the birth of Joseon Era.

Similarities:
-Both involve games that involve winning money
-Both are based on Japanese Manga's
-Both involve stuff that deals more on the psychological side
-Both very suspenseful
-Both involve genius male lead characters

Differences:
-Liar Game is less violent
-Liar Game has many different games whereas Animal World only has Rock, Paper, Scissors
-Liar Game is a televised show in the drama whereas Animal World is not televised
-In Animal World there is less team work being done
-Animal World is a movie whereas Liar Game is a drama
-Animal World is Chinese, Liar Game is either Japanese or Korean (depending which version you watch)
-In Animal World when the main character gets angry he sees himself as a A Badass Villain fighting Clown, in Liar Game nothing like this happens
-When the Clown comes out in Animal World there is a lot of CGI, you won't find that in Liar Game

They are both very much alike, I recommend both!

Well, if you liked The Golden Eyes, you may also like The Mystic Nine. It is also about the tomb raiding and both the male leads (Yixing and William Chan) are really handsome;-). Here Yixing (Zhuang Rui) is playing the role of Erye Hong. Quite popular among ladies just like Zhuang Rui.:-D

the is the similar to Angle's last mission: love ... here the angel is a female who saves the hero but becomes human with angel's some abilities

in both of them,the main character has depression .they are suicidal and kind of want to end all of their sufferings as it is being hard for them to coup with everything that are happening in their lives.And then they find a person/people who helps them to find new meaning in life and start over again.

both female leads in Joseon Survival and Live Up to Your Name are doctors, and they are both a time traveling drama

Wuxia, martial arts, strong Male lead, conspiracies and intrigue. Female lead is intelligent and badass and can support the Male lead. Romance and good side characters with decent side stories

Both titles have the main character moving from the city to the countryside and coming into themselves. In Koko ni Aru Shiawase it is a man in his late twenties while in Amachan it is a teen aged girl.

Both a female power type plot. Strong career women.
WWW more like a comedy while SKY castle is darker BLACK COMEDY/melodrama esque.

Both show some GIRL POWER.
WWW about 3 career women with search engines;
Busted is an unusual variety show that's more like a variety show & drama combo with a pre-written storyline under which the members solve crime detective problems/challenges. Alot of it feels more like watching a thriller detective drama than a variety show.
And PMY in season 1 was the one doing 90% of the work LOL while the boys failed most of the time. So girl power there. XD
