In ????????? news, Mark Lee announced ahead of NCT’s 10th anniversary that he has completed his contract and will be moving on to new things. This means he will be leaving both NCT 127 and NCT Dream, as well as all the subunits and side projects.
For non-kpop fans, this is like if Harry left One Direction, or better yet, if someone was simultaneously the lead in both NSYNC and BSB and left the groups.
