On December 24th, Super Junior-M's Henry shared a special Christmas gift with his fans. The idol teamed up with f(x)'s Amber to deliver a beautiful ballad full of their hopes for a better, brighter future. While Super Junior fans are well-acquainted with Henry's musical talents, Amber surprised many with her guitar-playing skills and rich voice (especially since she's known as the rapper of her group). Check out their holiday gift below! [Thanks to everyone who sent this in!]
