Previously, Heechul and TRAX's Jungmo suggested they might be coming back as their sub-unit, M&D (Midnight & Dawn), via Twitter as the latter asked if people were ready for Midnight & Dawn.

Since then, there hasn't been much word about a reunion... until now! �This time, Heechul posted a short video clip onto his Instagram that revealed a snippet of a laidback, slow tempo song entitled "Soul" through which his soothing vocals could be heard.

He wrote, "M&D-?(Soul)�#MnD#heenim#kimjungmo." �Check out the track below. �Are you excited for a possible comeback from the two?
