Last week we reported that 2AM's Seulong would make an appearance in a MV for 2wins title track ??? / Bleeding. Now, the official MV Teaser has been released. 2wins is a new Hip Hop duo consisting of members TopBob and BumKey. TopBob was a part of TBNY with Yankie but unfortunately their music had poor sales and disbanded. BumKey was given an amazing voice and collaborated with many of Korea's most talented artists including Epik High and Dynamic Duo. He was considered to be one of Korea's top vocalists until a major setback. He had surgery on his throat because of frequent complaints of sore throat but due to the doctor's negligence, he couldn't speak for some time and it took two years for BumKey to fully recover. Despite the trials and tribulations, 2wins is optimistic about the future. Many thanks to baka0chan for the tip.
