moon sunghoon, also known as david is one of nrgs rappers, before nrg debuted, he was a backdancer for hamohamo. his nickname is moon sajang, he enjoys golfing, writing songs, and computer games. hes currently a logo maker and posts on instagram under the handle @moonsinza.

he is the first member that caught my eye when i first started being a fan of nrg, he has a really nice rapping style and sings really well, especially for someone who is more focused on rapping. hes written songs like "eNeRGy" and is credited (along with myunghoon) for most of if not all of their raps
