Popular singer-actress Suzy Bae will sing a new song for the SBS TV drama 'The Time We Were Not In Love.' 

The upcoming single will be titled "Why Am I Like This," and will showcase Suzy's beautiful voice. The song will be the theme for the character Oh Ha Na, played by actress Ha Ji Won.

"Sung by Suzy, ‘Why Am I Like This’ is a midtempo ballad, with lyrics that represent the heroine Ha Na’s heart," said a representative from SBS, as reported by Inquisitr.

"We expect that Suzy’s clear and pure voice will affect viewers,"  the rep added. The ballad song portrays the feelings of Oh Ha Na toward Choi Won (played by actor Lee Jin Wook).

The OST will be revealed on Aug. 1, during the 11th episode. The Time We Were Not In Love airs on SBS every Saturday and Sunday at 10 p.m. KST.
