In what could be good news for fans of Sunny Hill, member Misung recently posted a curious tweet on her Twitter feed.

"What am I do~ing?" she initially posted, following it up a few minutes later with "It's a secret!!!!!! But! Soon! Hillers will have their minds blown...hehe..."

After coming back with "Goodbye Romance" late last year, we can't help but wonder if Sunny Hill is ready to stand on the stage once again. What could Misung possibly be teasing about?
