Our Times is like the Taiwanese adaptation of 'He Was Cool'. Both 'bad guy' leads; both clumsy and innocent female leads. And both male leads have 'pasts'. Both awesome and worth watching!

Both stories involve a marriage contract, but Prime Minister and I has less melodrama.

The story is almost same, but i think this one is more romantic than Ya Leum Chan because the female lead married a man only save his land lady's child(because she was in us and the landlady was in jail). Also she didn't have any baby from her fake marriage. The guy in this chinese series is really hot :P .

Similar situation except a guy is dressed as a girl! To pursue he career and gain popularity as an idol!

Back to take revenge plot. Both characters are rich and pretty organized in terms of the way the plan their revenge. The girl of course, while being their weakness, is also their only remaining tie to humanity.

Rich weird guy falls for poor, clueless girl. Rich Guy falls first and pursues her even though he keeps denying it. His behaviour is totally crazy that everyone who knew him wants to know if he went mad. He faces up to his feelings soon though, and takes care of his girl.

Both are boss-employee romance.

Overall, High-End Crush was sweeter, and more hilarious, with the male lead so confused and behaving abnormally.

Both leads end up with kids that change them for the better. In the movie it's about a teacher who is inspired to be a real teacher b/c of his students and in GI it's a gangster that gets a kindergarten handed down to him by his grandma - and he has to go from wanting to sell the place to saving it. - one is a movie and the other is a drama :)

Both are very game based. The characters are continuously faced with games (which relate to their current problems in the plot) and need to find a way to solve them (to move forward with the story; save someone or themselves, get something, etc).

similar revenge story that contains thrill and a psychopathic criminal.

Same main actress, same genres, same vibe !
(Both also feature Motai Masako).

These two stories revolve around a woman who starts running a restaurant on her own but quickly gets to work and live surrounded by loving people. The main differences I see are that Kamome Shokudo is shorter (as it is a movie) and is set in another country : Finland.

Both have a girl dressing up as a guy to go school in around the Joeson period. Both contain two people falling in love blah blah.
Snow Lotus is a lot shorter and contains past as well as present, all about reincarnation and loving people and dreams.
Whereas Sungkyunkwan Scandal is more focused on the girl dressing up as a guy and going to school, entirely in the past.

These dramas are from the same writer & director. Both are tragic, star-crossed, love stories. Both feature Kim Bum being the best, and the cutest, side kick ever!

story happened during the reign of king seonjo, and prince gwanghei. its interesting to see different portrayal of historical figures in different drama

Both tell stories of their adventure into historical sites with mysteries. The stories are very mythical and somewhat dark. The Ghouls tell the tale of experienced grave robbers while The Lost Tomb is focused on learning through the adventure as archaeologists. If you are looking for intensity then The Ghouls is definitely the one. If you are just starting out in the category of grave adventures then try The Lost Tomb.

As fellow OCN dramas, these shows share a considerable amount of similarities: (1) the beloved dark, gritty OCN ambiance, (2) tortured male leads with cryptic pasts, (3) an overarching mystery that is slowly unraveled within the story line composed of numerous smaller cases, (4) quick, brutal violence that is generally mob vs 1, (5) growth of the camaraderie between unlikely partners, and (6) I'm sure many other similarities that will be revealed as the season continues!
