As of December 2025, the biggest news surrounding former RIIZE member Hong Seung-han, known simply as Seunghan, is his highly-anticipated return to the music scene as a solo artist.

The RIIZE Controversy: From Debut to Indefinite Hiatus

Seunghan’s time with RIIZE, one of the most anticipated debuts of 2023, was tragically short-lived, overshadowed by a massive controversy that erupted almost immediately after the group’s debut. The issue centered on the leakage of private, pre-debut photos from his personal life, a recurring and often career-ending problem in the K-pop industry.

The Pre-Debut Leaks and Fan Backlash

The controversy began in late 2023 when a series of private images and videos were leaked online, allegedly sourced from his former private social media accounts. These pictures depicted Seunghan in situations considered inappropriate for a newly debuted K-pop idol by a vocal segment of the fanbase, including photos of him with a girl in a hotel room and images of him smoking.

The pictures, which confirmed he was dating and engaging in typical young adult behavior before his debut, triggered immediate and intense fan backlash. This swift, negative reaction from the K-pop community, particularly from a portion of the fandom known as BRIIZE, put immense pressure on the rookie group and SM Entertainment.

The Permanent Exit and the 'OT6' Demand

In November 2023, SM Entertainment announced that Seunghan would be taking an indefinite hiatus due to the mental pressure and responsibility he felt regarding the controversy, which was hindering RIIZE’s activities. The group continued to promote successfully as a six-member unit throughout 2024. However, a brief attempt at his return in October 2024 was met with further, aggressive opposition.

The fan sentiment, often referred to as the 'OT6' movement (meaning 'Only The Six' members), solidified the demand for his permanent removal. This culminated in the extreme act of fans sending funeral wreaths to the SM Entertainment building, symbolically declaring his career in RIIZE 'dead.' In response to the overwhelming negative feedback and to protect the group's stability, SM Entertainment officially announced Seunghan's permanent departure from RIIZE in November 2024.

XngHan Rises: The 2025 Solo Debut and New Artistic Direction

The biggest update for fans of Hong Seung-han is the confirmation from SM Entertainment that he is not retiring but is instead preparing for a solo career. This move allows the agency to retain a talented artist while separating him from the group that was so heavily impacted by his personal life controversy.

The Solo Artist: XngHan and XngHan&Xoul

Seunghan will be making his solo debut in the second half of 2025, with some sources pinning the release for July 2025. He will be promoting under the stage name XngHan, and his debut project is reportedly a collaboration under the name XngHan&Xoul.

This solo debut is a crucial step for the artist, giving him a chance to showcase his individual musical identity and creative control. SM Entertainment has stated that he is receiving full support and guidance for his solo activities.

Musical Style and Creative Involvement

Early reports suggest that XngHan’s solo music will lean towards electronic dance tracks—a genre he has expressed a personal liking for. This is a significant departure from RIIZE's 'Emotional Pop' sound, allowing him to carve out a distinct niche in the competitive K-pop landscape. Furthermore, XngHan is reportedly taking an active role in his solo preparations, including involvement in the writing and choreography processes. This level of creative control is often a hallmark of successful solo artists, suggesting a more personal and mature artistic output.

The solo debut represents a massive risk and a huge opportunity. While he faces the challenge of rebuilding his career and fan base outside of a successful group, his undeniable talent and the public's curiosity surrounding his return ensure that the XngHan solo debut will be one of the most talked-about K-pop events of 2025. It is a story of redemption, resilience, and the relentless pursuit of an idol dream, despite the harsh realities of the industry's 'cancel culture.'
