This was such a difficult song to sing! I can just feel my throat constrict at all the HEART TO HEART TO HEART parts, :x Can totally tell that my voice was strained, oops. Thank God I only had one 'HEART TO HEART TO HEART' part, poor Katiwa!
Anyway, well done, Bee! Mixing is not bad at all! Perhaps a little bit of timing problems at parts. & omo dongsaeng, your HyunA parts are super cute. :)
Everybody did good, yay! :D
