Same melodramatic vibe; same story of two individuals meeting and getting along but soon separated by tragic circumstances only to meet later in their lives; equally amazing soundtrack. By the end, only the seasons and the musical compositions in the titles are different.

Same concept (recycling old folk tales), different vibe. Cinderella's sister twists around the story of Cinderella, making you sympathize with the sister in a melodramatic tale. Alice in Cheongdamdong gives Wonderland a Korean name, and the White Rabbit a very nice human body in a not-sure-if-comedy-or-what story.

Same concept, different vibe. Who are you is on the suspense/action side while Master's sun is on the comical side, but in both cases, girls see ghosts and fall in love. In which drama I'd rather be? Who are you. The ghost might be freakier, but at least I'd kiss Taecyeon AND Kim Jaewook.

Same story, different time period. The two little girls are equally cute, but I choose Lee Jun ki a thousand times over Lee Dong Wook, sorry!

Same actor, same story, same vibe. Only the cast is different. Moral of the story: if you're looking for a dark, vengeful plot, always look for Kim Nam Gil.

If you enjoyed this drama you will also enjoy Joo Won's other project (Bridal Mask). Although is not a romantic drama it holds a lot of history and it's really really good. Personally i like to watch different dramas and movies from the same actor to judge him or her better as an actor.

You'll really get his full charm with this action-historical drama.

both the male leads falls in love with dead ex-girlfriend's sister

There's the same concept of the school sucking and being rivals with a better school (academic and baseball-wise). Also there's the same actors, Nakajima Yuto and Yamazaki Kento, once again on the same struggling team.

Tumbling also revolves around "Yankees" or delinquent-like students joining a team sport and struggling/working together. Also you get the same satisfaction of cute boys in tight gymnastic suits instead of tight speedos.

Both leads have a supernatural power and that's why they're using their power to save others. You can see a good-evil 'fight' in both dramas.

Another High School romance. MARS is slightly more angsty (but nothing too bad) and the feel is similar. And I would swear the filming location is identical.

well the acting is really good in both, they are both sad only this one is more sad they involve royals

Both are drama and movie about firefighter, though on movie 'the tower' only focuses on rescuing people inside a burning tower.

Both dramas are about doctors and nurses trying to save people outside the hospital though Dr. DMAT focuses more onto disaster cases.

They are both great movies and it all revolves around the Gwangju massacre on May 18.
