2PM dropped the full music video to their comeback single 'Promise (I'll Be)' after much anticipation. The group was teased for their comeback by their company JYP Entertainment. The company built up this comeback by posting an array of things via their Facebook page, to get fans excited for the comeback. JYP Entertainment began teasing the group's comeback on September 4th.

Before the official video release, an album spoiler was released. The album is titled 'GENTLEMEN'S GAME' has a very mature sound, represented by their very mature image. A few of the songs even give off a Michael Bolton vibe. This is the group's fifth album. For an album spoiler, their talent is exemplified.

The music video is one for the eyes, showing a very grown up and sexy image of 2PM. The song is an unexpected twist however, being much more upbeat than the image for this comeback. One could assume that the sound would have been a more easy listening kind, but nonetheless, it is still a great comeback song! Check out the video below!
