D-day, from�Danal Entertainment, who made their debut back in October, have�revealed a winter single titled "Just One Love".

"Just One Love", the work of Shin Kwang Soo, features the lovely voices of the female duo as well as�The Boss's�Injun.

The song itself is one that is easy on the ears with its addictive melody and sweet lyrics. It's also special in that rather than singing, Injun has decided to show off his hidden rapping talents. He helped write the rap as well.
