King & Prince will release their sixth single “I promise” on December 16.

This was announced on October 9 during their online concert ‘King & Prince CONCERT TOUR 2020 ~L&~.’ The title track is a Christmas love song that will be used for Seven Eleven’s 2020 Christmas CM. It’s about a man’s unchanging feelings for a woman even though romance between the two cannot be fulfilled. As the coupling track, the single will include “Winter Love Story,” which was the Christmas CM song for Seven Eleven last year. The other coupling tracks will be winter songs as well.
