It was a monster year for RM and the boys of BTS, who released their newest album, Love Yourself: Her, and made their mark on America, setting several milestones along the way.
ET talked to the band in November, where RM revealed why he chose to stop going by his previous moniker, Rap Monster.
"[Rap Monster] came from a song that I made from like, 2012, there was some phrase like Rap Monster, and I just, I thought it was so cool," he explained. "But as I grow up, and as I came to America, I think it felt like too much. So I just abbreviated it to RM, and it could symbolize many things. It could have more spectrums to it."
