'The Dream Chapter: ETERNITY' delves into the complexities of adolescence, capturing the internal conflict, pain, and fear of separation that often come with growing up. As the boys* navigate misunderstandings and experience cracks forming in their once-unbreakable bond, they begin to confront the harsh reality that not everything is permanent. Yet, despite these challenges, they hold onto the hope that their time together can last forever. The album reflects the emotional weight of change, emphasizing both the inevitability of growing apart and the enduring desire for connection. Drawing from TXT’s own experiences as trainees and rookies, it resonates with the struggles of pursuing dreams while navigating the difficulties of youth, perseverance, and the passage of time.

[*Within TXT's discography-based narrative the 'boys/boy' can be interpreted as representing the TXT members, but they also serve as generalized protagonists used to convey the broader experiences of youth.]
