Their story

Singles first

Mark spent years in NCT U, NCT 127 and NCT DREAM before anything carried only his name. "Child" came out in February 2022 through SM's NCT Lab project, and "Golden Hour" followed in April 2023. In May 2024 he released "200", and SM used the moment to confirm that a full solo album was on its way. In December came "Fraktsiya", a rap track with Lee Young-ji.

Four cities

The Firstfruit arrived on 7 April 2025, nine years after his debut. He called it autobiographical. The thirteen songs are arranged around the places he has lived: Toronto, where he was born, then New York, Vancouver and Seoul. He co-wrote the lyrics for every track, and the title song "1999" is named after his birth year. It sold more than half a million copies in its first week and won three music shows.

Leaving NCT

On 3 April 2026, just before his tenth anniversary, SM announced that his contract would end on 8 April and that he would stop all NCT activities. In a handwritten letter he said he was leaving to chase a dream he had carried since his trainee days, when he pictured himself busking with an acoustic guitar. He thanked the members, who had cheered him on, and promised to return in a new form.

Where he is now

In June he announced Upper Room, a creative company he co-founded and runs as co-CEO. Its first release, "My Friend", came out on 10 September 2026: a mid-tempo pop song built on guitar loops, far from the busy sound of his NCT years, and he wrote, composed and arranged it himself. He has also teased a pop project for children.
