Impact on Music Production and Unit Structure
Seventeen is known for self-producing, and the change in lineup influenced how units are formed for albums and tours. Vocal and performance units were recalibrated to reflect the current member composition while preserving the group’s diverse musical palette.
Joshua and Jun had contributed to writing and arranging, so their absence created space for other members to step into more prominent creative roles. This transition allowed the group to explore new sonic directions without losing their collaborative ethos.
The core production team, including leader S.Coups and other senior members, strengthened their roles in mentoring and guiding the unit formations. The result has been a more flexible structure that can adapt to different concepts while honoring the group’s legacy.
Current Lineup and Activities Post-Departure
Today, Seventeen operates as an eleven-member group with three distinct units: Vocal, Performance, and Hip-Hop. This configuration has enabled them to deliver polished performances and complex choreographies while maintaining vocal harmony at a high level.
Recent albums and world tours demonstrate the group’s cohesion and ambition. Members have taken on greater individual spotlight in songs, vlogs, and solo projects, showcasing talents beyond their unit roles in the broader group narrative.
The bond among the remaining members has deepened through shared experiences. Longtime fans note that the group’s connection feels more intimate, with each member’s contribution more visible and valued in day-to-day activities and stage work.

Seventeen’s fandom, Carats, has remained steadfast through lineup changes, supporting the group through social campaigns, streaming goals, and concert attendance. The relationship between the group and fans has evolved into a more mature partnership focused on mental health and honest communication.
Going forward, Seventeen is poised to balance new music, global collaborations, and individual growth. The departures of Joshua and Jun have set a precedent for handling personal needs with transparency, which may influence how the group approaches future challenges.
