tvN月火剧《无用的谎言》OST Part 4《이별하지 않는 사랑도 어딘가 있을거야 （An unbreakable love）》有凭借出色的唱功受到众多人喜爱的申容财（2F）的参与。

《이별하지 않는 사랑도 어딘가 있을거야（An unbreakable love）》 是一首刻画了恋人们的在爱情里画上所谓离别的句号时的心情的歌曲，抒情歌词让人留下印深刻的象 。歌曲把剧中金道河（黄旼炫 饰）与穆率熙（金所泫 饰）二人之间的关系细腻地描绘出来，提高了观众们对剧情的投入度。

另外，讲述拥有识破谎言的能力而无法信任他人的「谎言猎人」穆率熙，和没有任何人相信他清白的杀人嫌疑人金道河纠缠在一起，共同揭开真相的罗曼史《无用的谎言》将于每周一、二 8点50分在tvN播出。
