2. Stable Seven-Member Lineup Confirmation

Since their debut through I-LAND, ENHYPEN has maintained a stable lineup of seven members: Jungwon, Heeseung, Jay, Jake, Sunghoon, Sunoo, and Ni-ki. All major K-pop profiles, music news sites, and the group's official social media channels consistently list this seven-member formation, even in late 2025 and for future 2026 activities.

3. Confirmed Future Group Schedules (2025/2026)

ENHYPEN is confirmed to be part of the lineup for major upcoming events, such as the '2025 MUSIC BANK GLOBAL FESTIVAL IN JAPAN.' Sunoo’s name is included in these official lineup announcements, demonstrating his commitment to the group's international and domestic schedule well into the next year. His presence in these high-profile events is a clear sign of his long-term role.

Understanding the Root of the Sunoo Leaving Rumors

If the evidence is so clear, why do these rumors persist? The speculation is not based on official statements or actual events, but rather on a combination of past temporary absences and fan-driven narratives that often circulate within the K-pop community. Understanding the origin of these rumors is key to dismissing them.

The 2022 Health Hiatus

The most concrete event that sparked initial 'leaving' fears was Sunoo's temporary suspension of activities in August 2022 due to health concerns. BELIFT LAB released an official notice stating that Sunoo was experiencing "poor physical condition" and symptoms like dizziness and headache, requiring him to rest and recover. This was a temporary hiatus, and he returned to group activities once cleared by medical professionals. However, any time a popular idol takes a break, even for health reasons, it unfortunately fuels speculation about a permanent departure.

Mistreatment and "Left Out" Fan Narratives

A significant portion of the persistent rumors stems from a narrative among some fans (ENGENEs) that Sunoo is being mistreated, sidelined, or "left out" by the other members or the agency. These claims are often based on subjective interpretations of interactions in vlogs, behind-the-scenes content, or live broadcasts. While these concerns reflect the passion of the fandom, there has never been any official confirmation or substantial, objective evidence to support these claims, and other fans often point to strong bonds and respect among all seven members.

The "New Era" Discussion

Interestingly, recent fan discussions in late 2025 have centered on Sunoo having a "new era" and "coming out of his shell" within the group. This positive discussion about his increased confidence and spotlight is the opposite of a departure, suggesting a strengthening of his role and presence in ENHYPEN's future. This narrative focuses on his growth as an artist, moving beyond previous "aegyo member" labels and demonstrating deep trust and respect from his fellow members.

Conclusion: Sunoo's Position in ENHYPEN is Secure

The question "Is Sunoo leaving ENHYPEN?" can be answered with a definitive and resounding No. The evidence, particularly his full involvement in the upcoming 'THE SIN : VANISH' comeback scheduled for January 2026, and his confirmed participation in future group activities, completely invalidates the rumors. Sunoo remains a vital part of the seven-member ENHYPEN lineup, continuing his role as a main vocalist and performer. Fans can look forward to his continued success and growth with the group in the years to come.
