Just in case you haven't heard of the awesome duet on their first single Chu~?, f(x) members Luna and Krystal sang a duet called You Are My Destiny. When the promotions for Chu~? started, I was sad because I knew that this song would never be performed, but, surprisingly, my wishes came true! On the January 6th broadcast of Live Session, the two cuties blasted out to a live orchestra and band and I have to say, they killed it! The young duo has some real TALENT! f(x) also performed Chu~?, LA chA TA and Chocolate Love. Check out all the performances below: Chocolate Love: You Are My Destiny: Chu~?: LA chA TA: Thanks to heartfx for the videos and shout-out to our friends over at Aff(x)tion!
