ボーイネクストドア / 보이넥스트도어
BOYNEXTDOOR write about falling for someone, getting it wrong and trying again, in language close to how people actually talk.
Last updated:
ZICO runs the label, and the group keeps the distance the name implies — the songs stay conversational even when the production gets big.
Choose this if you want plain-spoken lyrics instead of worldbuilding, with the story continuing between releases.

What anchors BOYNEXTDOOR is the closeness of a boy who lives next door and plain words pitched close to speech. KOZ Entertainment, led by ZICO, debuted the six-piece in 2023, and the start of a crush, the failures, the parting and the will to move forward once more all arrive through everyday lyrics and bright staging.
The way in is One and Only, But Sometimes, Earth, Wind & Fire. Going from the light self-introduction of the early days through the momentum of heartbreak to an unpredictable structure shows a group that keeps a story running rather than one that merely sounds fresh. Japanese releases raise the count on both sides too, among them BOYLIFE, SAY CHEESE! and the work titled "AND,".
IF I SAY, I LOVE YOU in 2025 widened the contact with a mainstream audience. Official footage from THE FIRST TAKE and the STUDIO CHOOM family fills in the voices and the performing. One and Only, then Earth, Wind & Fire, then IF I SAY, I LOVE YOU covers the self-introduction, the pleasure of the structure and the reach into the mainstream.
Editors' take One and Only / Earth, Wind & Fire / IF I SAY, I LOVE YOU — a KOZ six-piece who keep a story running through the closeness of the boy next door and words pitched like speech.
No. 96 of 210 groups with recorded activity in Japan (top 46%)
The denominator is the 210 groups, out of 525 covered by KPOP DISCOVER, whose raw score reaches at least one point. The score adds 10 points per Japanese-market release, 3 per Japan-related track, 12 per member from Japan, and 8 per official Japanese account. Japanese-market releases carry the most weight because they are the most direct evidence of activity; related tracks add track-level detail; members from Japan stand for Japanese-language communication and continuity; official accounts stand for a permanent point of contact. The weights are an editorial judgement, not a statistical optimisation, and the ranking tracks release volume in Japan closely.
