Debate has erupted within the fandom of ENHYPEN following the sudden departure of member Heeseung, with some fans proposing a “black ocean” protest during the group’s next major appearance. The controversy comes as the group continues activities without him, prompting intense divisions over how supporters should respond.

The discussions began almost immediately after the group’s label Belift Lab confirmed on 10 March that Heeseung would halt group promotions and pursue solo work under the same agency. While some fans launched petitions and protest trucks outside HYBE, others suggested in-person demonstrations during upcoming performances.

Proposal for a ‘Black Ocean’ sparks backlash

ENHYPEN is scheduled to perform at the Hello, Melbourne festival on 14 March at Flemington Racecourse in Melbourne, and the news that Heeseung would not attend intensified frustration among sections of the fandom, ENGENE. A circulating plan encouraged fans to stage “7 minutes of silence”, remaining quiet after the first two songs, lowering lightsticks and holding up the number seven.

Some observers warned the gesture closely resembled a “black ocean”, one of K-pop’s most severe forms of protest, historically seen as a direct message of disapproval towards artists on stage.

Many fans immediately condemned the idea, calling it harmful to the remaining members. One wrote, “It's NONSENSE. wdym you're planning these quirky plans?? i mean yeah that's good if you're aloudly reminding belift that #enhypen_is_7 and bringing heeseung's name along the concert. but NOT in these ways. please also respect the other 6 members and think about their feelings.”

Fans divide over protests

Opponents of the planned silent demonstration highlighted that the group’s leader Jungwon had privately urged fans to continue supporting them during a recent video call. Many argued that a black ocean would do little to influence company decisions and would instead demoralise the remaining members – Jungwon, Jay, Jake, Sunghoon, Sunoo and Ni-ki.

The potential impact on member Jake, who grew up in Australia and has repeatedly expressed his wish to perform there, also drew attention. Fans warned that staging a black ocean during one of his most meaningful career moments would be unnecessarily hurtful.

Timeline of Heeseung’s exit and group response

Belift Lab had stated that Heeseung wished to explore a different musical direction, and that the agency respected his choice while keeping him signed as a solo artist. The singer later confirmed the decision on Weverse and posted a handwritten letter thanking fans and reflecting on six years with the group, since their debut in 2020.

The remaining members then shared a joint message on X, saying their time together had been meaningful, expressing respect for Heeseung’s decision and assuring fans they would focus on their upcoming commitments.

The agency also told Billboard that concentrating on solo activities was “the most suitable path”. ENHYPEN resumed schedules the same day with a video call event, though Heeseung’s slot was removed.

Shortly afterwards, Belift Lab temporarily paused new episodes of the group’s YouTube series En-O’Clock, announcing it would return in April. The six members were later seen departing Incheon airport on 13 March, confirming their travel to Australia for the festival.

What is the ‘Black Ocean’ in K-pop?

A black ocean is one of the most severe expressions of fan disapproval, occurring when audience members turn off their lightsticks and fall silent during a performance. In K-pop, where synchronised lightstick displays symbolise support, such a gesture is widely interpreted as a public rejection of the artists on stage.

Historically, several groups have faced black oceans, including Girls’ Generation in 2008, BTS in 2016, Seventeen in 2015 and others. While the acts rarely damage long-term popularity, they are known to deeply affect performers.
