Sixth OST is out for the currently airing drama Lookout. I Need a Light is a beautiful ballad that combines both sadness and hope. It’s produced by Whee (Park Byung Gun) – a lyricist and composer, who’s also famous for being a Mensa member with IQ of 160. The song was meant to express how people are able to find hope in the most unfortunate situations. This theme shadows the main plot of the drama, where the characters struggle in life after losing their loved one due to crimes.
