Siwan will be participating in an OST for his drama 'Tracer'.

Siwan, currently gearing up to return to the small-screen in his Wavve original drama 'Tracer', plays the role of a man named Hwang Dong Ju. The character is a young chief who works at the National Tax Service, a place known to be scarier than the prosecutor's office. In addition to starring in the drama 'Tracer', Siwan will also be lending his voice for an OST in order to heighten viewers' immersion into the drama. 

The lyrics of the original soundtrack "Fire" was written from the perspective of Siwan's character Hwang Dong Ju. Resembling the refreshing personality Dong Ju shows in 'Tracer' when uncovering dark secrets, "Fire" will likely deliver catharsis to listeners.

Meanwhile, 'Tracer' is scheduled to be released through Wavve on January 7 and will also be broadcast on MBC.
