Artistry
BoyNextDoor's music has been self-described as "easy listening and natural". Members Jaehyun, Taesan, and Woonhak actively involve themselves with the production of the group's music and largely aim to create music about "the daily lives of their peers". In the group's First love trilogy of Who!, Why.., and How?, BoyNextDoor explored a narrative of "first love and heartbreak", with Who! serving as an exposition, Why.. detailing the story's ending, and How? bridging the narrative between the two releases. The tracks from the trilogy were largely influenced by rock, teen pop, hip hop, hyperpop, and synth-pop.
