Both dramas show a female lead character pining for a true love. The true love arrives via a magic book, however in Emperor or Boss that book turns out to be a prop in the end. Both transplanted true love interests live with the FL & are supported by them. One may be a cartoon hero & the other a prince, but both deliver love.
Emperor or Boss is a super cute shorter drama with a surprisingly fun plot/ plot twist. It involves a mysterious emperor that somehow lands in modern society due to a wish in a strange journal. They embark on their journey, both female and male lead helping each other in ways that will benefit both parties. However, adapting to this new world is harder than it seems and on top of that, her boss is involved?? She tries her best to keep everything going, and to not lose her job in the process. Although, this is mostly centered around the modern era setting we get to see a fusion of ancient china/wu xia vibes. Both incorporate the use to an emperor falling into modern society, adapting and naturally falling in love. It's super cute to see their interactions and how the differences they bring to modern society. Emperors and me, gives you multiple dynasties, a longer and more intricate plot including a change in modern vs ancient times setting.
