Er..

Let me stop the christmas fever first and let me introduce you to Doojoon & Dongwoon here. Although I'm not a big fan (or even a little of it) of B2ST, but I had to admit their song are nice (you know, beautiful). The new song is by both of Doojoon and Dongwoon, which I don't know who is who and I never really heard both of them before. Enjoy! XD
