Both dramas are similar and of high quality in many aspects from the beautiful set visuals, actors, costumes, music to the story. Of course NIF1 is also there (maybe higher) with the quality but it is too different on the story side. Enjoy!

- Both dramas revolved around a female-centred cast.
- Both dramas is set in an upper class setting.

Well, the stories are completely different. But they have the same director, and there's a similar feel here and there. Though SIMAAF seems much better (it's still airing as I'm writing this XD). If you just want a lighthearted rom-com, give MSR a try. Personally, I liked it very much.

Although not a body swapping thing, it does involve a high school girl going to the past to Joseon time and becoming a eunuch because of a misunderstanding, is put to work directly for the king and the two fall in love. It does involve water as a medium of time travel, both series have that. It also has the FL trying to help the ML to rule as a wiser king, both series have that. And in both series the king becomes a influential ruler that affected korean history because of it. And instead of bringing culinary skills to the past, she brings modern day math and science knowledge.
