BOYNEXTDOOR expands the concept of 'home' from a physical place to a relationship through their debut full album 'HOME'. The music video for lead single 'Knock Knock' depicts home as no longer a safe space, revealing the reality of inescapable external threats. Through four concept films, members search for home ('NAVIGATOR'), attempt to create their own space ('WEAVER'), and hide in a bunker isolated from the outside world ('BUNKER'). Finally, in the 'SWEET HOME' film, they realize "within this confined space, we have built something that finally feels like home." The album includes tracks such as 'Remember Us (Forever You)' about family, '06070' documenting trainee days, and 'I Wonder' expressing feelings toward fans. Their 'HOME' is redefined as a relational space where their most precious connections gather, while conveying mature messages about the weight of dreams, uncertainties in family relationships, and the impermanence of life.
