Conforming Doyoung’s second release as a solo performer, “밤공기 (Night Air)” is a sweet rock-ballad song featured in the original television soundtrack of 심야카페 (Cafe Midnight)’s third season, titled The Curious Stalker, in which Doyoung made his acting debut as the main character, Son Ji Woo.

The melancholic track, which follows the plot of the fantasy drama and is supposed to describe protagonist Sun Min’s feelings towards Son Ji Woo, touches the subject of the time-transcending longing for somebody, as the narrator wonders if they could get a second chance with that person.
