^^^ Those UFO messages... The girls did fanservice by breaking all the popular pairings.
There was one asking Jess to choose between Yulsic and Taengsic, and Jess said Tae was her only love, then another reply from Yuri saying like "What are you talking about? Yulsic? That's gross!!" (Not exact words but something to that extent.) Now that's 2 shots at my Yulsic. ;_;
Then there was another asking Yoona which pairing she thought was the best (no choices), she said "Yoonyul". That probably broke the hearts of all Taengyoon shippers at snsdchina (there are lots, it seems). But I like this pairing too
. Then there was another one for yuri, I don't understand what it meant, but Yuri's reply was "Yoona is mine" (or my Yoona...I'm not sure).
