NCT DREAM debuted on August 25, 2016, with “Chewing Gum” as NCT’s teenage unit. Their original concept included a graduation system, meaning members were supposed to leave the group once they reached a certain age. This led to one of their most difficult moments in 2018, when Mark had to leave NCT DREAM. It was especially emotional for both the members and fans, as they had grown up together since their debut.

In 2020, the graduation system was abolished and Mark returned, bringing the seven members together again. It became one of the most meaningful moments in NCT DREAM’s history. With songs such as “Hot Sauce,” “Hello Future,” “Glitch Mode,” and “ISTJ,” the group grew from a teenage unit into a successful adult group. They achieved million-selling albums, major tours, and international recognition. Their journey wasn't always easy. Health-related hiatuses, the pandemic, and the pressure of being artists brought difficult moments along the way.

Today, NCT DREAM represent youth, friendship, growth, and togetherness. They didn't simply grow older together — they grew up together.
