Mark reflected on the difficult decision, describing it as “not a closing door but rather an opening new one,” while acknowledging that the change is both exciting and frightening.

He emphasized that his choice was made with careful consideration, adding, “I’m not playing here, and I am for sure not playing with your guys’ hearts.”

The rapper also reassured fans that they remain at the forefront of his thoughts, promising to work hard moving forward and to make his journey meaningful.

“I’m truly always thinking about you guys and I’ll really be working very, very hard to make it all make sense,” he shared.

Mark concluded his message with a simple but emotional goodbye, “Love you all so much… See you.”

SM Entertainment posted a statement on Weverse, confirming that they and Mark have come to a mutual decision to “conclude his exclusive contract as of April 8.”

He will finish all of his active projects or activities with NCT, including NCT 127 and NCT DREAM.

SM also said that NCT 127 will continue as a seven-member group and NCT DREAM will continue as a six-member group.

Mark originally joined NCT in 2016. He released his debut studio solo album The Firstfruit in April 2025.

Here’s the full text of Mark’s statement.

Out of all the things my heart wants to say right now, I truly wish to say thank you. Thank you for loving, supporting, and shaping me to become who I am today.

I truly believe that our hearts have better sight than our eyes, and what my heart sees right now isn’t a closing door but rather an opening new one.

I hope our next chapter together could be where we are all healthily smiling about the past, welcoming the present, and being excited for what’s to come. It’s a quest that I myself am scared about, but I know that it’s not for the worst. If I had ever done something right to have gained your trust over the last decade, I hope you believe me when I say that I’m not doing this just for fun….

I will never forget the pieces of love and truth each and every Czennie gave me… I’m not playing here, and I am for sure not playing with your guys’ hearts… You guys make me want to be a better person, and I hope my decisions in life can only become a positive impact to anyone watching.

I’m truly and always thinking about you guys..and I’ll really be working very very hard to make it all make sense.

Love you all so much….

See you
