Ever since Yubin made a post to Instagram on December 9, many Wonderfuls have been hoping to see the Wonder Girls together again soon. She posted the above photo and the message, "The king of baby hairs. Practice and practice again." Considering there were previously rumors that the Wonder Girls would make a comeback as four (Yubin, Yenny, Lim, and Sunmi) this past fall, her post definitely got fans excited.

They responded, "What kind of practice," "Possibly a comeback," "It's been a while. Please return soon," and more.
