A fancam has recently surfaced of a male fan suddenly going onstage during a Girl's Day concert while the four-member group was in the middle of singing their hit 'Darling'.

At around the 30-second mark, the crowd starts to get louder. Then, five seconds later, a male runs up the front of the stage and takes a position beside Sojin. What happened next was shocking. The fan starts flawlessly dancing along with Girl's Day in line with their choreography, to the amused cheers of the crowd. At 1:09, he takes a spot next to Sojin again, who is filling in for Hyeri's absence at the concert. Netizens speculate that Hyeri was busy filming for her upcoming drama Reply 1988.

The fan continues dancing until the song completes and take a bow along with Girl's Day, even giving Minah a double high-five right before the video ends.

Some Korean commenters believe that the MC of the concert brought the fan onstage, stating that the man with the microphone that ran up on stage alone with the fan was the MC.

Props to Girl's Day for making a fan's dream come true!
