YeoJin changed her voice by inhaling helium!
How about GoWon?
GoWon's voice is already in helium!
Trying again!!
Her voice didn't change much...
Yves- [new] auto-tuned version!
It's so funny~!
Yves' voice so young!
GoWon trying again with her strong will!
It sounds like my voice?
It's her voice every time we hear it!
I'm sure I drank it all???
