While the series had a high viewership on Netflix in more than 50 countries, it received minimal attention in South Korea, where the show takes place. A reason cited for this was that the global success of South Korean media led to the country's people not caring about its depiction in foreign productions. Another explanation was that thrillers and action shows are more popular than romance shows in South Korea.
