The song starts of with a simple, slow-tempoed intro and then picks up when Ayumi starts to sing. Keiko then joins in for the chorus. This song pretty much stays the same after that with the duet alternating from one verse to the other until it builds up to the climax near the end. The two singers' voices contrast greatly yet they work very well. Ayumi's being soft and flowing while Keiko's loud and more mature. A touching ballad, just perfect for the holiday season.
