Girls’ Generation’s Yuri left a message online, which netizens are quickly guessing that a new sub-unit is currently in the works.

On June 25, she posted a photo of member YoonA and herself on her Instagram along with the message, in English, “Coming soon, yoonyul, ilikeyou.”

She previously uploaded a picture on the same account with the short caption, “Recording.” The picture shows a close-up of a lyrics sheet on a stand with a lot of notes written all over it.

Soompiers, what could “coming soon” mean?
