I heard that an OST sung by Wooseok himself is finally coming out. Did everyone hear the news?

They say the song "Parallel Lines" sung by our Wooseok will be officially released on the 15th.
I've been waiting ever since I liked your voice when you briefly appeared in the preview for episode 10.
I already knew he was good at singing, but hearing it in Grand Prince Ian's voice is a whole new experience.
Since we can listen to the full version the day after tomorrow, we should all get ready to stream.
I think I'll be even more immersed in the drama while listening to Wooseok's voice, so I'm already looking forward to it.
