It has been some time since 4minute's Hyuna went solo and performed her single, Change but she did an impromptu performance of it recently, delighting fans. On May 13th, Hyuna turned out for Yonsei's AKARAKA event when the music for Change started playing. This wasn't scheduled at all and although fans started cheering 'Go Hyuna', she hesitated until 2AM's Jinwoon came up to her and begin rapping to ease the awkwardness. After hyping the fans, Hyuna continued dancing to her hit song despite wearing a tight black dress and high heels. http://www.youtube.com/watch?v=9BbN4JMYbfE Stay tuned to allkpop for 4minute's comeback stage with Huh on M! Countdown tonight! Let's hope for some interaction between Hyuna and the Wonder Girls.
