Question: are nct and nct 127 the same?
Answer: 127 is a different subunit that's also a part of NCT. Taeyong, Mark, Jaehyun, and Taeil basically rotated from “U” to “127”, while WinWin and Yuta were added as new members. 127 has a very “hard” hip hop heavy sound. During their comeback, Doyoung was rotated into 127 and a new member, Johnny, was added.
