both kinda break "gender roles"? SWDBS has a freakishly strong female lead that saved the day and caches the male lead when he falls. while TTON has a male lead that disguises as a woman and he looks soft and pretty.

recommendations are not just about similarities. if you watched mr sunshine 1st, then her private life could be like healing medicine?, and if it's the other way around then please beware, mr sunshine is not a romcom ;p
but both male leads have that serious yet dorky side? and both female leads are strong and independent women~

both are romcom office dramas. both female leads are independent and smart though granted, no one can beat mr lion :)

Both have many political schemes. smart protagonists and you always crave for more eps!

In Nirvana in Fire, the protagonist succeeds in every situation while in Royal Nirvana, the main character fails a lot and you suffer more when you watch it.

Both are excellent in their own ways :)

Both protagonists are very smart, come back with different names and plot a revenge against all people who crossed their ways.

if you liked one of these then you'll surly enjoy the other too. they are not really that similar in plot or characters, but as someone who always looks for dramas with great female characters, I love connecting these dramas ;)

Kim Soon Jung had that strong confident in her work kind of vibes, which is kinda similar to Woo Ah Jin.

both have real strong independent women leads. though I'd like to give Nam Jung Gi more credit, he is kinda like Woo Ah Jin's husband? they are both naive and pushovers? it's not a bad thing though, for MTANJG ;p

these 2 dramas also have that "cold blue" dark tones. one is female centered and one is fully male centered, but both are character driven stories

talk about woman power~ both are female driven stories with multi layer female characters. recommendations don't really need to have similar plot, but they are both awesome ;p

there are dramas that have a "cold" tone to it. they are relaxing and somewhat as realistic as dramas can get?

great dramas need to be connected together even if they don't share much in common. both of these dramas are high quality masterpieces. and both have interesting and strong women

both of the main leaders of a gaming team, but in gank your heart the main female is a female livestreamer but i have only watched the first six episodes there are 30 something episodes in total. I recommend it if you like this drama

Both have the same dating style and story development.
Both male leads are working at a high ldvel of management position in their offices.
Plus both ML are good in showing two sides of their attitude

This is a drama I can proudly say takes the mantle from Nirvana in Fire. I am privileged to watch this gem.
