You don’t often see a K-pop idol close a decade-long chapter with a handwritten letter. That’s exactly what Mark Lee did, confirming he is stepping away from NCT and SM Entertainment after 10 years.
The message feels personal, direct, and emotional. Mark calls it a “team leave,” thanks fans, and hints at a new phase ahead. For fans who watched him grow from trainee to global performer, this moment lands with real weight.
The Moment That Changed NCT Overnight
Mark announced his departure through a handwritten note shared on April 3, 2026. Instead of a corporate statement, he chose to speak directly to fans.
Here’s what you need to know:
- He is leaving NCT group activities
- He is parting ways with SM Entertainment
- He described the decision as a “team leave”
- He expressed gratitude toward fans, members, and staff
This matters because Mark has been one of the most consistent and visible members across multiple NCT units. His exit is not just a lineup change. It reshapes how the group looks and sounds going forward.
