Love Whisper was released in 2017 as the title track of Parallel, the fifth mini album by GFRIEND, a six-member South Korean girl group who debuted in 2015. The song became known in the K-pop community for its energetic choreography performed in water and its pure, schoolgirl concept that had defined the group since their early hits. Clips from the track later circulated on soundboards and in fan edits, where the short, bright excerpt is reused as a recognisable musical cue by listeners who follow the group.
