Hyun Ah couldn't attend the Mnet 'Mcountdown' encore stage for placing 1st once again for the song 'Trouble Maker'.

During the actual performance Hyun Ah gave a sexy performance with Jang Hyun Seung, but her absence on encore stage caught the attention of many.

CUBE entertainment associate revealed "Hyun Ah couldn't attend the encore stage because she had another schedule she had to tend to".

On this day, Jang Hyun Seung, the other member of the duo Trouble Maker, got on the encore stage with A Pink, in place of Hyun Ah.
