Girls' Generation's Yuri and YoonA are coming soon?

Yuri wrote a cryptic message on her Instagram, posting, "Coming soon #yoonyul #ilikeyou," along with a snapshot of the 'YoonYul' couple.

Fans commented, "YoonYul, take more photos," "Don't do this, it's killing me, " and "You're both so pretty!"

What do you think Yuri meant? Maybe the next possible Girls' Generation subunit following TaeTiSeo?
