Both are very short film.
The film end where the romance about to start.
Sweet young couple met at unique situation.

Old man in the movie has Alzheimer.
People in the neighborhood seems to know
The old man still wondering around, kind of in and out of his dementia

Both drama’s are about female leads who get bullied for their unattractive looks and later become attractive but have to hide their true selves. True Beauty is about a teenager while Perfume is about a middle age woman. In both shows, the male lead loves them just the way they are.

Mad for each other seems more like a comedy at the beginning but gets more serious as the show progresses. Just Between Lovers is more melodramatic. Both shows have a love story about healing and people struggling with mental health issues. JBL shows PTSD and alcoholism while MFEO shows anger management issues, paranoia, PTSD and social anxiety.

Both are military survival competitions, although the concept is a little different
Both have very similar drills/games/missions
I think The Soldiers was actually spun off from the Iron Squad because of it's success.
I think Iron Squad is much better imo as you get to know the contestants more, there's MC panelists, and more heart, but if you're in the mood for more military competitions, then try the Soldiers.

Both of these shows have an emphasis on sci-fi and augmented reality. There is a rich developer and a normal girl whose paths intersect. There is action in both shows, however Memories of the Alhambra has more sci fi action, and my Holo Love has a lot more romance.

Both productions feature quirky professional killers and the way relationships and people influence them

They have a very similar vibe: very intense, people get hurt, you can really feel the chaos and stress of the characters who are just trying to survive. Choi Woo Shik plays in both too.

Both dramas deal about infidelity and marriages being tested. Both show the struggles of a woman, who has to find her way out of a huge gap that opened up.

It has the same plot that involves twins and identity switch . Also , the same male lead is both of them.

If you liked Jang Hyuk as Lee Bang Won and want more - try this.

one is tv series, another movie, in both Jang Hyuk plays Lee Bang Won and is amazing. Of course same time period and historical events.

in both except for Jang Hyuk/Lee Bang Won there are 2 male leads (in tv series Jang Hyuk isn't listed as main lead, but he is quite main character and star of the show, though not only star because 2 young leads are also amazing and bromance is best ever)

Both dramas are about people who are trying to survive as well as fighting against the capitalist system. And they have the image of love for the homeland.

They are similar since Miman Keisatsu is an adaptation of Midnight Runner but instead of a movie, it was turned into a series.

In both dramas both the female leads are writers. They both travel from modern time back to historical period. The romance of Tiger and Rose is really good!! The story actually makes sense and more believable.

In both dramas, the female lead travel back from modern time to historical time. Both have romance. But Oh! My Emperor is so much better!
