The group SF9 made a surprise release of the music video for their new song, "Good Guy."

SF9’s agency FNC Entertainment released the music video of their new song "Good Guy" on their official YouTube channel on Jan. 6. Unlike the usual way the music video is released at the same time as the release of the song, the company decided to make an unusual debut with confidence in new concepts and visuals to mark their first full-length album.

The released music video is set in a social club of "GOLDEN RATED," where only SF9 can be granted. Dressed in a neat suit, SF9 will play sports such as tennis, football and pool to have a golden bracelet. The nine golden bracelets the members won marked a new beginning for SF9 that eventually became one, though they compete for the bracelet.

In this process, SF9 maximizes its ‘Good Guy’ fantasy by focusing on goals and competing gentlemanly. Also, the portrait-frame screen reminiscent of a pictorial, and the modern visual beauty of black and white tone, not only accentuate the cool physical average of 181 centimeters in height, but also focus attention on the visual itself of SF9.

As the music video was released in advance, YouTube views of Good Guy's music video soared last night, drawing much attention online. Amid the trendy and understated sound of Good Guy in the music video, fans are excited to see how the sensuous performance, which has become the trade mark of SF9, has evolved.

Along with the music video for "Good Guy," SF9 released the highlight medley of their new album, revealing their confidence in their full-length album. The highlight medley, which contains the musical vision of SF9, has drawn attention from fans as it was revealed that SF9 members participated in the entire song.

SF9’s first full-length album ‘FIRST COLLECTION’ was released on major music sites at 6 p.m. on January 7, the day after the MV’s unusual preview.
