[All] NCT Mark's voice is like a cave

I keep listening to NCT Mark's part because his tone is so good

Mark's tone is this good, his voice is like a cave tooㅠㅠ

I'm glad I found out, even if it's late.

There's a lot to look for in the future, and he's also good at dancing.

I saw the challenge and it seems like Mark is an all-rounder. I'm into him.
