they were both filmed in the same way and have the same characteristics (probably because most jdramas are filmed this way). they both have the idea of a family/couple moving into a new a place which causes them a lot of trouble (by trouble i mean murder). even main posters are pretty much the same. they both also show many people in creepy ways. like they have characters who are different when you see them and when you walk away (if you get what i mean). plus, some characters have weird habits and objects so that leads to almost everyone becoming suspects.

the only difference is that anata no ban desu shows a whole block of flats and all the mysterious things that happen to each one and character/s living in them whilst shinhannin flag focuses on one family and the murders surrounding them.

also update : shota and nana (the main two from anata no ban desu) have a small guest appearance in episode 8 of shinhannin flag :)

Private lives is one of my favorite Netflix dramas. Especially if you love the action thriller romance.

Both dramas have a female lead who is focused on her career. Hae Ryung works at the palace, and so (eventually) does Cheon Gi. Both female leads fall for a man who at first glance seems more soft/gentle, while the female lead is more strong willed and ambitious. (Though, in Lovers of the Red Sky, Ha Ram isn't really as soft and gentle as he may seem.) And both dramas start out with more focus on the female lead's professional aspirations and on the blossoming romance before transitioning to a greater focus on political intrigue and more angst.

That said, the tone of Rookie Historian Goo Hae Ryung is more comedic and down to earth than the spooky vibe of Lovers of the Red Sky.

Similarities:
- A strong female lead in an action packed movie taking bloody revenge without minding her own wellbeing.
- Lots of fighting blood and violence

Differences:
- human trafficking and abduction with sexual abuse of the abduckted (read the taggs before watching)
- FL trying to safe the abducted younger sister
- no law enforcement authories involved

Both are short south korean 2021 about a romance between two guys dramas/series. Centers around the culinary art and/or food.

Both are Strongberry/Matchbox productions focusing on a same gender romance. Theyre both about high school graduates and very sweet and cute! They also came out around the same time and can be watched on youtube for free.

Same kind of calmness and tranquility
Male and Female leads leaning on each other through hardships.
Healing, precious and sincere,
nicely written and executed.
Both were MBC weekend dramas that aired in the same year... hmm

Goblin is a more mature, much darker series in the way it tells Kim Shin's origin story and fate. There is a lot more slapstick comedy in the first few episodes of MRIAG that may deter someone who's looking for a more mature series, like Goblin, but I'd suggest sticking through it for a few episodes as the FL in MRIAG matures a bit and dies down on the excessive humor. I really enjoyed both series. Goblin's OST is *leagues* better (I'm still listening to it on repeat) as is the overall story, which I found had more depth and bittersweet storylines that made me feel more engaged. That said, I really really liked Gumiho as well, and despite how beautiful Goblin is, Gumiho had a much stronger plot/antagonist and I thought the ideas of fate and love had wonderful tie-ins to both shows.

Both shows about female leads who were once successful in their field of work but suddenly a psychological state they fall in make them feel uneasy and in perpetual depression.
The female leads have problems with their husbands who are leaning to their first love.
The female leads were pregnant and had miscarriage which make difficult form them to return being hardworking.
Both dramas have in common mystery and ambiguous sides in the sequence of events.

Another action-filled show that illustrates how two characters on the opposits of the law, Cop<->Villain find common grounds and a little bit of romance.

Same with the 2003 version: The main similarity is the on/off mode of our main character and their need to hide their insecurities and personality traits they think that contrast their "perfect" image(if you ask me everyone shows a different face depending on where they are anyway) . Another similarity is the sweet/demanding persona of the mls. Also older woman/younger man trope happens in both.

Another similarity is the sweet/demanding persona of the mls. Also both drama have a younger man/older woman romance.

Both drama are about a "perfect" capable career woman who just wants to sit back, relax and be a total mess inside her own house(gym clothes+beer+manga= happiness). Romance that makes our heroines both become comfortable with showing their true self and slowly make some space in their life for the male lead. Some up and downs but basically both are short, fun and sweet drama with a dose of ridiculous moments of course.

If you are missing Fiery Priest already, have a little stop-over in One The Woman. Everyone is still patiently waiting for TFP 2, but One The Woman looks like a spin-off with Lee Ha Nee's character in focus.
I swear, if you loved Le Ha Nee's role as a prosecutor, you will definitely be satisfied with One The Woman focusing on the female prosecutor's story.

-Kikazaru... is a similar story set-up as Cha-Cha-Cha, except the leads are the late 20's versions of the lead couple from the latter (who are in their mid-30's). The high-flying city girl, and the homely, earthy and grounded boy with opposing sets of values!
-The FLs land as a tad superficial; fashion and self-image obsessed. The MLs are pretty low-key in comparison, and often give our FLs wholesome critiques which causes them to evolve and not be so uptight.
-Plenty of found-family themes. The story-telling is paced like slice-of-life in both.
-The lead couples have a very youthful, playful dynamic. Their bickering sessions are fun to watch.
-FLs have a previous 'crush', they look up to and immensely respect, but they mistake familiarity and nostalgia with 'love'.
-The MLs are initially reserved in their affection. Both have bouts of jealousy, but FLs are very reassuring in their feelings towards the ML!!!
-Both FLs are extremely career-oriented & independent. Both face immense repercussions at work due to a small incident, at different points of the series.
-Both MLs suffer from heavy emotional trauma (although slightly different reasons). The outcomes are the same though, both retreat from their successful & regular full-time careers, and currently operate only as self-employed part-timers. Like quirky twins, Chief Hong has his 'off-days' and Shun keeps his food-truck open on 'weekdays and whenever it doesn't rain.'
-Both FLs help our MLs overcome their traumas. Likewise, the MLs cause them to become more likeable and soft eventually!
-The couple's 'dreams' clashes in both. However, they eventually can settle on a mutual middle-ground!

BONUS: The first episode epilogues in both the series is the EXACT same. While the leads look like they don't really get along, and are as different as chalk & cheese, the MLs have almost the exact same reaction to our FLs, when they realize the women aren't as superficial as they seem. That's the initial point of attraction between both couples... <3 <3
