SM Entertainment are remaining tight-lipped regarding Taeyeon's next comeback, but that hasn't stopped her putting out music with man-of-the-moment Crush.
The two have paired up for the R&B singer's comeback single, "Don't Forget," a beautiful ballad about keeping treasured moments in your heart forever.
And while the Girls' Generation singer doesn't actually appear in the video (apparently there were schedule conflicts), her sweet vocals pepper the track throughout.
A rep for the singer says, "Their voices blend together beautifully and fans will certainly enjoy hearing their collaboration."
The video was shot during a recent trip to Japan, with beautiful winter scenes taking place against Mount Fuji and even the streets of Tokyo.
