CUBE Entertainment has fans scratching their heads today after the release of a mysterious new teaser video.

At midnight KST on October 11 the agency posted a teaser video to their official Twitter account featuring 4Minute member Gayoon and top model Kim Won Joong.

Of the 39-second teaser they said, "Is this a photoshoot or a movie, Gayoon and Kim Won Joong's affectionate couple acting! Who is the individual behind the vocals? 'Right There' 1st MV Teaser."

From the looks of the brief glimpse, Gayoon and Kim Won Joong appear to be portraying a couple who are parting ways.

There are a few theories floating around among netizens and fans, the most likely being that the teaser video and new song are connected to "K-Pop Star 2" contestant Shin Ji Hoon who signed with CUBE a few months ago.

Shin Ji Hoon's fans are eager anticipating her official debut and have their fingers crossed that she is, in fact, the voice behind the vocals in the "Right There" teaser.
