Mnet's "Reply High School" will finally lift the veil of its first broadcast at 8:20 p.m. on the 13th.
"Reply High School" (directed by Shin Hyo-jung, Jang Eun-jung, and Cha Jae-min) is a time-slip reality in which SM Entertainment's 15 trainees, SMTR25, experience culture from the 1990s to 2010s in the virtual school "Ujung High School." In the first episode, which airs today, the boys who have time-slip in each era are unfamiliar, but they are fully adapted to the friendly classroom landscape, depicting the first day of school.
In the pre-released video released earlier, members who are overly immersed in the world view are being captured, raising expectations for the first broadcast. In the classroom, where the classical atmosphere is completely reproduced from iron desks, green blackboards, and wooden floors, members of the 90s class are curious about the "direct city" mark on the map. Eventually, when one member whispered, "Let's ask ChatGPT," the rest of the members said, "What is that?" and tried to protect the world view of "UJUNG Go" and made people laugh.
Talks over the menu of school meals also bring sympathy. When Jaewon mentioned the episode of the school meal, saying, "I had a lot of fun thinking it was seasoned chicken, but there were times when it was Kodari Gangjeong," the scene where the members sympathized with each other, saying, "I've been tricked a lot," reminds me of school memories throughout the generation.

The heated discussion of each class looking at the class schedule is also an important point to watch. In the 90s, when students feel sad about going to school on a Saturday, and in the 00s, when they are excited about "Is this Saturday Nol-Saturday?" and until the 10s, when they came up with their own interpretations of unfamiliar subject names such as "passing (integrated science), "tongsa (integrated society)," and "chang (creative experience activities)." Boys' reactions in the same school and different times naturally recall each generation's school days.
The first day of school, "Entering the dormitory," will add full-fledged fun. In the "Mugunghwa Flower Bloom" game, which is unfolded to occupy the desired bed, the members pass through the limbo and engage in a fierce battle with the tagger to burnish their desire for victory. In particular, the images of boys throwing themselves to acquire golden items that will improve the quality of life in the dormitory are expected to be the highlight of the first broadcast.
Curiosity for the main broadcast is at its peak, as to whether SMTR25 members will be able to enter the "Ujung High School" safely and what kind of reversal will be revealed in the veiled dormitory life.
The "Reply High School" production team said, "The unexpected consensus and wild reactions that trainees show while living in an era they have not experienced are the biggest fun of the program. Please watch whether SMTR25 will be reborn as the perfect student of "Ujung High School" through today's broadcast."
The first episode of "Reply High School" will be broadcast on Mnet and Mnet Plus at 8:20 p.m. on the 13th.
