Tracer OST Part.5 Fire is a medium-tempo song that goes well with the pleasant drama content, and it directly contains the emotions of Hwang Dong-ju (Yim Si-wan) in the play.

This song, which is expressed in a dreamy yet colorful feel by putting a delicate piano on a light brass and rhythmic beat, has improved the perfection by participating in composition and arrangement by Nuvocity, a composition team that shows new songs in various OSTs every time.
