Both are dramas with a modern day FL who is magically transported to historical times where she meets and falls in love with the ML.

A modern doctor and a Joseon era acupuncturist (his name written down on history) travels between the past and present time. They each learn more about modern and traditional medicine from their experiences

Both are mini dramas with a modern day FL who finds herself in history in the body of another girl. Both MLs are royal.

- The FLs are so similar in personality, kinda crazy/kind/innocent.
-But they're (FLs) both capable, one from being a doctor, the other for knowing the plot of the story.
-MLs are initially cold, but adorably sweet when they fall in love & MLs fall in love first
-Both are time travel dramas... sort of.
-Both have the main characters marry each other early on & fall in love with each other

I think Tiger & Rose has a lot more comedy than PAL, but both are super light watches.

Both are mini dramas with a modern day FL who is magically transported to historical times where she meets and falls in love with the ML.

Both FLs are modern day women who transmigrate into the body of a historical woman who is married to/marrying the ML.

Both dramas have the FL occupying another girl's body, and a royal ML with a stoic personality.

They have a very similar feel to both dramas. Both female wake up to find themselves in another world. Both FL seem to a pretty much the same personality ....

Both the main male lead dislike the female lead at first but slowly develop feelings for her after they overcome so many obstacles. Main female lead came from another different dimension/timeline but was absorbed to a different era to meet the male lead. Both drama are somehow short and very straightforward about the climax. These 2 drama has the same emotionally feelings after watching it. Both drama also seems to have season 2 because the ending was cut short and needs more explanation in the overall drama.
Some differences I spot in these drama is that one has more Official soundtracks than the other and one is more emotionally sad in the middle. The drama Unique Lady has 5-6 soundtracks and sad in the climax compare to Princess at Large, there is only 2-3 tracks also the climax is not sad. And finally came to realize that in Princess at large the female lead meets the male lead in her dimension while Unique lady, they never show any presence time in modern clothing making the storyline mysterious. But hopefully there really is season 2 of these dramas. ?
