Both have a group of diffrent girls that live together and make an leal friendship on youth time~

Both movies have people that loved each other and had to separate but after a long time they meet again~

Also accused for a crime he didn't commited. But is more focused during prision.

both have time travel genre, there's also a diary involve that owned by main lead actress of this two drama, the difference the way they time travel is that in Faith a doctor is being forced by someone to time travel while in Thousand Years of Love a princess who wants to die, time travel instead. they also have bitter sweet ending

Both dramas involve the suicide/possible murder of a high school student and work to unveil school corruption. Angry Mom is lead more by the adults while Solomon's Perjury is lead by a group of students. Angry Mom is a bit darker than Solomon's Perjury, but both have some humor and romance in them.

It is gender bender. As is you're beautiful female lead disguises herself as male

Both very good mystery dramas with great acting. Suspense is also good. The mystery is entertaining and they both leave you off of your seat thinking about what's going to happen in the next episode. Both also have strong female leads!

Same feels. Both about crimes, but Voice is a bit more realistic (no element of magic or time-traveling). Also, both use the same font.

Both of these dramas have similar main characters, fake relationship and contain funny scenes.

Based on the same Manga.But the story follows only the basic outline of the manga and all the other things are messed up like character development, emotions ect.In my view if you love the Japanese drama then you are going to hate this film.

Based on the same Manga.First adoption of the Manga,, but the ending differs from the Manga as the Manga was on going at that time.

The Lost Tomb, The Mystic Nine and this one is all base on the same novel series.

It is base on the same novel series. I would recommend watching Mystic Nine first.

Mystic Nine is the prequel on the same novel series. It is also very very good.

In both dramas we follow the lead protagonist as he get's hired in a big company. It's interesting because we get a glimpse of how a Korean company works (conformism, hierarchy...)
While Jang Geu Rae is not qualified for the job ang introverted, Chief Kim is talented and extraverted.
