Block B‘s Zico and Girl’s Day‘s Sojin recently collaborated on an OST for SBS Wednesday-Thursday drama “Mask.”

“Mask,” which has held on to its first place ratings spot since its first broadcast on May 27, has already gained attention for its first OST “Just One Day,” which ballad queen Lyn sang and wrote the lyrics for.

Written by Zico and Sojin, “It Hurts” (working title) begins with soft piano and guitar, capturing listeners from the very start with Zico’s soft rapping and Sojin’s emotional vocals which complement each other well.

Check out the OST below, and share with us your thoughts! What do you think about Zico and Sojin’s collaboration?

“Mask” airs every Wednesday and Thursday at 10 p.m. KST.
