I'm already looking forward to Byun Woo-seok's voice being revealed on the 15th.

I can finally hear an OST sung by Byun Woo-seok.
I got goosebumps even more because I saw an article yesterday saying it was a hidden card that wasn't even in the existing lineup.
I was actually thinking while watching the drama that it would be nice if there was a theme song for Grand Prince Yi An, and sure enough, there is.
I should get ready for endless streaming when the song comes out this Friday.
Let's all soothe our sadness over the drama ending with Byun Woo-seok's song.
