Reply High School

Reply High School is a time-slip growth reality show following 15 boys who dream of leading the future of K-culture as they enroll in a unique “school” to find the answer to debut. Through a special curriculum designed to win the hearts of fans across generations, they journey back through the defining eras of Korean pop culture—from the birth of Hallyu in the 1990s, to the golden age of the 2000s, to the global rise of Korean stars in the 2010s. More than a simple retro experience, the boys must fully immerse themselves in the emotions, style, and spirit of each era. And once the lessons are over, the real challenge begins: living together 24/7 with no eliminations and no going home, they eat, sleep, struggle, and grow side by side as they prepare for a festival stage of their own.
