## Reception

Despite being touted as "the next Love in the Moonlight", The Emperor: Owner of the Mask failed to emulate the latter's success and to achieve the same ratings, despite the extensive promotion and hype the series received before its premiere. However, while its competitor, during some weeks, managed to outperform it in some categories, such as the 20-49 year old demographic, as well as streaming, popularity and brand reputation charts, the latter enjoyed modest viewership, while The Emperor: Owner of the Mask still managed to top the ratings in its time slot. William Schwartz of HanCinema stated that the series is "irredeemably stupid", adding that "...the obstacles the characters run into are never clearly defined. It's one of the reasons why the resolutions in this drama are so unsatisfying. There's no tension." Despite some expressing dissatisfaction with the story and the production as a whole, viewers praised the performances of the cast.
