Everyone in NCT 2018 was learning the choreography for Black on Black. One member was missing and that was Jaemin.

He was doing a quick check up at the doctors because he complained about his back. The members practically forced Jaemin to go because they really didn't want anything to happen to him yet again.

The next part was a bit tricky and required full focus of the members, or else one of them was going to fall off. 

They were making a tower, with Yuta, Mark, and Taeyong standing on top. If they could actually pull it off it would look amazing.

All the members were paying attention as people tried out their towers little by little. It wasn't all at once because they needed practice. 

When it was the group she was in, they stood by the choreographer. They started showing everyone the positions as the others took a break.

"Mark, you're going to have to step on Jaemin's back but he's not here at the moment. So we can't really run this part."

The room went dead silent, and you could here a pin drop.

"Excuse me?" Mahina said lowly.

The choreographer ignored the girl, looking at his blocking sheets. Mahina's eyes flashed as she walked up to them and tapped the clipboard.

The words that came out of her mouth shocked everyone and no one at the same time. "Replace Jaemin with me."

The man let out a laugh. "Honey, you aren't strong enough to do this part. Jaemin will be fine." He waved it off like it was nothing. 

Mahina was SO close to punching the dude, and everyone in the room felt it. "I'm sorry sir, but did you know Jaemin JUST got back from a back injury. I'd prefer- and I'm sure the fans and the members agree with me- that he don't do this part." 

Mahina was spitting out words in the shocked man's face. "Plus you don't know how strong I am now do you. So re-block this part and put me in Jaemin's place."

The choreographer opened his mouth to protest when he stopped. Glares were hitting him all over the room. 

From Mahina, to Mark, to Taeyong, to Jisung, everyone of the members was glaring at him. 

It was as though they daring him to oppose the group.

He stuttered at last, "F-f-fine." He fixed a murderous glare on Mahina. "You little brat, I won't forget this." He said low enough for only the two to hear.

Mahina smirked letting out a growl. "And I hope you never do."
