After teasing and then releasing his music video earlier this week, Battle member, Zin Taehwa kickstarted his promotions with his debut stage on the 8th October episode of Mnet's M! Countdown. Having been spoilt by Zin Taehwa as he went from blonde to black in his music video for his angel and devil concept, he stuck to his devil concept with black hair and outfit this evening for his debut performance. And Mnet had to spoil it with some mic problems along the way, but Zin Taehwa rode out that obstacle and managed to put out a pretty hot stage. Many thanks to Jaeurazn for tip.
