Isn't Mark really cool? How can someone be so cool?

Mark, who used to shout "you doo!!!" with a young face in the seventh sense, when did he grow up so much? Mark is good at rapping and dancing really well. When I watch the choreography video, I can't help but look at only Mark~ The dance line itself is pretty, but the control of dynamics is lacking. But his singing tone is also good. I don't know what he lacks. He must be really busy with 127 and Dream activities, but he's also consistently doing solo activities. He's amazing! I'll support all of Mark's activities in the future.
