[All] The reaction to the IU♥Byun Woo-seok duet is exploding. Please release an album.

IU and Byun Woo-seok doing a duet in *The Grand Prince's Wife*—isn't that seriously cheating? Haha.
I feel like I immediately understand why the reaction demanding an album exploded the moment I heard it.

I was surprised that the two of their voices matched better than I expected.
If the song is actually released like this, I think I definitely have to listen to it!
