Apink recently came back with their new album 'Horn' with the title song "Dilemma."

For the promotions of the album, the group appeared on M-Countdown on 17th February, where the full group(Apink), as well as sub-units within the group(JooJiRong & YOS), performed their respective songs.

During the performance of "Nothing" by Joojirong, fans noticed Apink's leader Chorong's kind gesture towards her backup dancer.  In the fancam video released by M2, she was seen wiping her dancer's leg after she stepped on the leg (as a part of their choreography) during their performance. Many fans commended her actions on stage because of this incident.

Here's a snippet of the said incident:
