what is the difference between nct 127 and nct dream and nct u?
Alright now, NCT 127 is a fixed group (for now, unless SM adds members). NCT 127 has 9 members; Mark, Taeyong, Winwin, Jaehyun, Johnny, Taeil, Doyoung, Yuta and Haechan. ... All the members in NCT Dream are teenagers and there are 6 members. (There used to be 7 members as Mark used to be in NCT Dream but he left.)
