On April 3, 2026, SM Entertainment dropped a bombshell that sent shockwaves through the K-pop world. Mark, one of NCT’s most beloved and versatile members, is leaving the group. His exclusive contract with SM will officially end on April 8, 2026, marking the end of an era for the Canadian-born rapper who has been a cornerstone of NCT since its debut.

Mark shared the news through a deeply personal handwritten letter, pouring out his raw emotions after a decade of intense activities with NCT 127, NCT DREAM, and NCT U. In the letter, he reflected on his journey that began on April 9, 2016, when he stepped onto the stage as part of the limitless concept group. From his early days as a trainee to becoming a global force known for his sharp rap skills, stable vocals, and undeniable stage charisma, Mark has been one of NCT’s most consistent pillars.

In the heartfelt message, Mark opened up about his long internal struggle. He wrote that over the past 10 years, he achieved far more than he ever dreamed possible, but he began questioning what his ultimate dream and purpose in life truly were. “Throughout these 10 years, I’ve had so many stages and memories. Naturally, I started thinking about the greatest dream I could ever dream, what I should do, and what the best purpose I can have in my life is,” he shared.

He expressed overwhelming gratitude mixed with sorrow. Mark thanked his fellow NCT members for sailing together on the same ship through the most wonderful journey. “I’m so thankful and I love the members who have been with me on this incredible ride,” he wrote, adding that just thinking about them brings tears to his eyes and that he feels sorry for the rest of his life. He also extended sincere thanks to the fans, known as NCTzen, who have supported him since his trainee days, including the SM Rookies period, making every single day of the past 10 years filled with happiness.

Mark emphasized that his start in the music industry was deeply tied to SM Entertainment and NCT. He recalled beginning his music path 14 years ago in Canada and discovering his best self through the company and the group. Despite the difficult decision, he promised to never forget where he came from. “I will always be a Mark who never forgets his beginning,” he stated with quiet determination.

SM Entertainment confirmed that the decision came after long and careful discussions. The agency revealed that Mark had been contemplating this move for some time, and all NCT members fully supported his choice after open conversations. The company expressed respect for his personal growth and future ambitions, while wishing him continued success in whatever path he chooses next.

Fans were left stunned and emotional. Many NCTzen took to social media to express a mix of heartbreak, understanding, and pride in Mark’s bravery to pursue new dreams. Some recalled his unforgettable performances, solo releases since 2018 that showcased his musical range, and his role as a reliable all-rounder who could rap, sing, dance, and lead with ease.

Mark’s departure adds another layer to the evolving story of NCT. As the group’s “limitless” concept allows for flexible member activities, his exit raises questions about the future direction of the units he was part of. At the same time, it highlights the intense pressure and personal sacrifices K-pop idols face after years in the spotlight.

In his letter, Mark hinted at wanting to explore different musical expressions, possibly returning to his roots with more street-style performances, guitar playing, and English songwriting. He hopes to live with continued gratitude toward everyone who shaped his career while stepping into a new chapter as his authentic self.

As the K-pop community processes this news just days before the official contract end, one thing remains clear: Mark’s impact on NCT and global fans is unforgettable. His journey from a young Canadian trainee to a beloved superstar has inspired countless people. While fans mourn the end of an era, many are already excited to see what Mark will create next.

The full handwritten letter has been widely shared, with fans treasuring every word as a final loving message from their idol. Mark’s story serves as a reminder that even the brightest stars sometimes need to step away to chase even greater dreams.

Whether this marks a temporary break or a permanent shift, Mark leaves behind a powerful legacy within NCT and the wider K-pop industry. Supporters worldwide continue to send love and well-wishes, hoping his next chapter brings the fulfillment he has been searching for.
