On December 17, some lucky fans and passersby saw Yoona and Cha Eun-woo shooting something near MBC Headquarters in Sangam-dong, Seoul.

They were there surrounded by lots of cameras for ages, and were constantly seen laughing with each other during breaks.

It happened during shooting when they had to stare into each other's eye.
While doing so, Yoona took a step back, but lost her balance for a second after missing her step.
She immediately burst into laughter and covered her mouth in embarrassment.

He then tried to get rid of it by stepping on the sticker with his foot.
Yoona, however, unfortunately failed to notice what Cha Eun-woo was doing for her, because she was too busy laughing.
A few seconds after that, Yoona's staff rushed to remove the sticker on her shoe.

It is assumed that Cha Eun-woo and Yoona were filming a teaser video for MBC's annual end-of-year music festival 'MBC Gayo Daejejeon' in which they were chosen as the hosts for the third consecutive year.
