"Red Light, Green Light." A phrase familiar to Koreans, yet unknown by foreigners, has made a worldwide debut. This is all thanks to Squid Game, a Netflix drama series that has been streamed worldwide. Squid Game has captivated audiences throughout the globe with its mix of popular Korean children's games and death game genres to present something fresh. The “Dalgona Candy Challenge” has now emerged as a global game, and Korea's most representative character in textbooks Young-hee, has become a sensation. Not to mention that Red Light, Green Light has also become the world's most used horror background music.
