Woo I'm really excited for this, something about her is so intriguing.
I hope it is something similar to 4 Walls. Knowing Krystal it's probably going to be super artsy and just sooooo aesthetically pleasing.
On a side note, not to stir up drama, but I just wonder if this has anything to do with Amber's recent posts about getting zero attention from the company. I know her and Krystal and super close friends so she's probably not upset with Krystal, but it must really sting to constantly be asking to work and then have your group member get a solo (along with Luna getting a ton of work right now too with collabs and tv shows)
