Kyungmin's jump rope, the blood, sweat, and tears shed backstage

I don't know where Kyungmin got the confidence from, but he said he would do the jump rope version of the challenge tomorrow.

And then, backstage, he boldly grabbed a jump rope and started practicing.

At first, my steps kept getting tangled, but I didn't give up and kept going.

In the end, you practiced until you were drenched in sweat and succeeded. That's amazing.
