The producer shared the exciting news via Instagram on October 12. 

With a photo of 'Blue & Red', J.Y. Park explained, "Watching her sing on my show 'Party People' I thought to myself, 'How can she sing with so much emotion?' After a couple of days, having her voice stuck in my head, I sent her a song called 'Regrets' feeling strongly that she would understand the emotion behind it. And she texts me back 'I cried so hard as soon as I heard the song. I really want to sing it!' That's how 'Regrets' was born. Get ready people Monday noon! :)"
