The music video we have all been waiting for is finally here guys! They tortured us with the 9 second teaser a few days ago, and now the full music video is released, and it definitely does not disappoint! The little love story that unfolds in this music video around Ariel Lin as Super Junior's Siwon's old love, and Donghae's new love is the perfect story line for the soft, slow song called "Firefly". As we had expected, the song sounds sweet and lovely, and her pretty face and charming voice are just the cherry on the cake! Hopefully Ariel will garner more fans from this music video than anti-fans because we all know the ELFs are screaming and ripping their hair out from jealousy. Let's love, guys, love and appreciate.
