It is news that NCT's Mark is preparing to stand on his own.

Mark's NCT and SM, with whom he spent 10 years

I've decided to leave..

It's sad news, but...

There are probably things they want to do as well...

Conveying the news of my withdrawal personally through a handwritten letter..

He also expressed his gratitude to NCT and SM.

Mark, standing on his own two feet..

I hope your new beginning is even better.

Good luck!!
