SPEED's "Sad Promise" music video has become a hot topic after being released.
After being released at noon on January 7th, SPEED's drama and dance music videos created a huge response from the public and SPEED soon topped at #1 the real-time search rankings, including at GomTV, Naver, Daum and Nate.
"Sad Promise" is the work of the popular composer Duble Sidekick and features Davichi's Kang Minkyung. Her calm and sweet voice contrasts with the powerful rapping of SPEED.
Kang Minkyung also made the promise that if the song can appear in the top 10 of charts, she will buy a new mobile phone for all the SPEED members because of how hard they worked.
