After we did the shoot, the manager took us to one of the practice rooms.

The manager gave us a computer with some stuff in it. There were also lyrics on the side.

Manager
ㅡYou are going to do a collaboration! I keep you surprised to know who it will be with. The other idols of the collaboration wrote the lyrics and did the productions. The job they go or left is to do line distribution.

Hikaru
ㅡOkay!

ㅡBut we don't know the voices and positions of other idols...

Manager
ㅡTry to do the best you can anyway.

Yeseo
ㅡLet's go!

We started to read the lyrics of the songs and to distribute everything as evenly as possible.

After two hours, we were finally done.

Bahiyyih
ㅡWe're done! Can we leave now?

Manager
ㅡNo. I want you to start learning the dances. There are 5 songs, and therefore 5 dances. You won't leave this studio until you know them perfectly.

ㅡWhat?? But we can't! That would make us finish too late! And tomorrow, we have a fanmeeting!

Manager
ㅡI know. But you have no choice. I'll leave you alone with your dance teacher. I'll be in the next room if you need anything.

The manager left and the dance teacher came inside. We started training.
