As previously reported, Heechul and Jungmo will be reuniting as unit group M&D with a special appearance by G-Friend's Yerin in their upcoming MV!  It was reported that the boys have already finished recording the song and filming the MV, so Heechul shared some behind-the-scenes photos from the MV that he revealed he personally directed.

He wrote, "Heechul, who became the director of M&D's MV.  The subject of this MV is the story of love in your twenties.  We truly had fun all day filming.  The female lead is G-Friend's Yerin.  She's really pure and cute.  However!  In my heart, all of you are definitely first.  Hahaha.  See you in China."

In the picture, there indeed is G-Friend's Yerin having a fun time with Heechul and Jungmo, but interestingly enough, there are also shots of SISTAR's Bora and KARA's Hara, both of whom were revealed to have visited the set for a nice chat.
