Taeyeon has everyone excited because she may be hinting at a comeback!

She recently uploaded a photo of a butterfly with its body in the form of a microphone and its wings as a '3' onto her Instagram. Fans think that it may signal a comeback of some sorts, especially with the caption that read, "#3 #9 #butterfly #TY #Taenggu #soon".

People are taking the '#3' to mean the 3 members of subunit TaeTiSeo, and the '#9' to symbolize Girls' Generation. The 'soon' probably means that the girls are going to be doing something soon, and it's got everyone excited!

Do you think their newest concept - whether it's TaeTiSeo or Girls' Generation - might have something to do with a butterfly?
