Black now goes by the stage name of JM so I don’t know what you would like to call him. Usually I use the previous name but if they don’t use it anymore then I don’t know if I should too? Still the same person anyway. ^^
As requested, I put up his profile info but it’s not that I don’t know who he is and it’s not like I don’t like him. I also made his thread on Soompi. It’s sad that he didn’t get to perform much but he is still very young so I still see a good future up ahead for him.
