Public image

With each member debuting in their late teens, BoyNextDoor was envisioned with a "boy next door" image.^[1][2][11] While the group initially drew comparisons to the similarly conceptualized girl group NewJeans, such comparisons were later discredited upon their debut, owing to the group's "self-produced" nature and their dance styles.^[57] Kim Jae-heun of The Korea Herald attributed the group's success to their "engaging storytelling, strong performances, and TV variety show appeal", which he deemed as defining characteristics of the group.^[58]

Music styles

Members Jaehyun (pictured left), Taesan (pictured middle), and Woonhak (pictured right) actively participate in the production of the group's music.

BoyNextDoor's music has been self-described as "easy listening and natural".^[59][60] 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".^[61] 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.^[62] The tracks from the trilogy were largely influenced by rock, teen pop, hip hop, hyperpop, and synth-pop.^[62][63][64]

In 19.99, the group began to focus on self-expression and introspection, reflecting on their experiences and anxieties around toward growing up.^[65][66] The following release, No Genre, was characterized by homages to the group's musical influences.^[67][68] While the group maintained an emphasis on storytelling with emotional depth, the EP explored pop subgenres including pop-soul and city pop.^[67][68][69]
