I'm really looking forward to Byun Woo-seok singing "Parallel Lines" himself.

Even just the brief clip in the trailer had such a great vibe that I kept thinking about it, so I'm already excited now that it's finally being officially released haha. The reaction to the OST for "Sunjae, Carry Me and Run" was amazing, so I think this one is going to be just as emotional!!
Byun Woo-seok's voice feels clean yet conveys emotions so well, so I think it suits the drama's atmosphere perfectly. Especially since "The Grand Prince's Wife" is a work with deep emotional depth, I think the immersion will be incredible once the OST is added!!
The title "Parallel Lines" just seems meaningful for some reason, so I'm really curious about the lyrics and the atmosphere haha. I guess I'll just have to wait until the 15th!!
