After School leader Kahi solo album has been delayed. After School Kahi solo album scheduled to out on mid-november, and has been delayed.
The reason for this was Kahi wasn't able to find a song that she really likes. Even though many composers have come forward to give their songs to her, Kahi wasn't able to find the "100% perfect song" for her solo project.

We hope Playgirlz will continue to wait, anticipate and support leader Kahi's solo album when it is finally released, whenever that may be.

We will update once Kahi going to release her solo album!
