Recommandations

they are different but yet somehow certain things give you the same "feelings" as you're watching the drama - MDSY is definitely Unique and I don't think it could be "fully" compared to another drama. but there are "little" similarities in certain things - not a lot mind you - but if you liked MDSY - you should be the type that would like this drama too.

They are both revenge dramas but while the main character is getting their revenge they fall in love and learn secrets.

(Kamen Rider Kuuga) Theme is Dark, it shows Kuuga evolving into a Rider and Ultimately didn't become what he was supposed to become and went on a journey to recover his smile. which is sad because he was such a happy go luck guy.

(Kamen Rider Ryuki)If you are looking for a Dark Drama with Mature Theme and you like to sob your little fangirl or fanboy hearts out, then this is for you my friends! I like it because it shows us all the dark side to us all with wanted to have a chance to fulfill a wish for a loved one or what have all the while you are fighting others and your inner self for the Final Wish at the end on that long and hard journey. The Finale will clearly satisfy those that truly love and stuck through the whole series! I liked it eventhough I shed some tears in the latter episodes.

Both shows are about a detective who sees ghosts of the victims. The ghosts help in the investigations. In both shows the mood is a bit on a dark side.
The main difference pretty much is that BORDER is a Japanese show while Ghost-Seeing Detective Cheo Yong is a Korean one... with all the usual consequences. Also, the ending [which I am not going to spoil here] is not really similar. Otherwise, pretty decent ghost detective stories, both of them.

It is always best to see how it all started! This was my first Japanese drama and I loved it! It was really cute and adorable. Also it is awesome to marathon when the second season is done...

both drama revolves around undercover operations and jung kuyng ho plays in both.

First half of dramas have quite similar atmosphere, similar characters, but second half of SFftS is not so good.

both focus on the scheming of wives in a household. The settings both take place in a family known for their herbs and the male leads took in their true love in as a concubine. Complicated relationships, revenge, schemes, women power. Everyone is just fighting for their own position and the wives only want their husband to love them.

Quirky gender-benders with handsome men, romance and idol actors.

Both are melodramas in which the main characters first meet in their teenage years, being each other's first love, then they get separated because of some tragic events and meet again after years.

Both are ridiculous but have real emotion and some bitter-sweet life lessons

Both shows have two childhood friends experiencing the worries of life after the young years. Furthermore, both include love triangles and women in beauty industry.

the main characters in Inborn Pair (Chris Wang & Annie Chen) & the main characters in Fated to Love You (Ethan Ruan & Joe Chen) are alike in some ways. They were strangers when they met, but because of an incident, they gotten to know each other better. They got married to each other, but they have a marriage contract of one year. Later, they began following in love with each other.

Both stories are exciting revenge tales. But they're also quite different.

Both series are thrilling revenge stories staring Kim Nam Gil. If you like one you will undoubtedly like the other. ^.^
