A K-pop fan influencer has died by suicide during a deeply distressing TikTok livestream, following a wave of harassment from supporters of a well-known boy band.
Mina Chan, a Japanese social media personality living in South Korea, died in the early hours of August 5.
Known to followers online as sweeter_nk, Chan had built a visible presence within the ENHYPEN fan community.
She ran a popular fan account, frequently appeared at concerts and fan-sign events, and was especially known for championing Ni-ki, the group’s Japanese member.
In the days leading up to her death, however, sections of the fandom turned against her amid claims she had crossed personal and fan boundaries.
The backlash reportedly began after Chan attended a late-July ENHYPEN concert in the US, where she tried to have member Sunoo pass flowers to Ni-ki.
The moment triggered fierce criticism online, with detractors accusing her of drawing attention to herself and attempting to overshadow the concert experience.
Scrutiny around Chan escalated after Ni-ki appeared on a Weverse livestream on July 30 and spoke about appropriate concert etiquette.

The singer, who did not name Chan directly, spoke disparagingly about concertgoers who were more focused on receiving personal attention from the group than enjoying their performance.
He said that it risked damaging the energy of a concert, which only sparked further backlash for Chan online.
In the aftermath, the dedicated fan posted a lengthy apology on X that read, in part: ‘I feel like my actions ended up taking advantage of Sunoo’s kindness.
‘I’m truly sorry. I feel so apologetic toward Sunoo and all the Sunoo fans.
‘By attending ENHYPEN’s fansigns multiple times, I had deluded myself into thinking I was closer to the members than I actually was.
‘I deeply regret the rude behavior I exhibited in America. I ruined the atmosphere of the venue by prioritizing my own desire to meet Ni-ki over the precious time Ni-ki, who loves America so much, deserved. I’m truly sorry.
‘To everyone who has supported me as sweeter_nk until now, thank you so much.’
Police received a report at 5.33am on August 5 concerning a Japanese influencer in her 20s who was attempting suicide during a TikTok livestream, according to South Korean news agency Yonhap.

One wrote: ‘Rest in peace, Mina. You didn’t deserve this. You were a kind and lovely person who had a big heart. I hope you are free and found peace.
‘My heart goes to your family and friends who had to face your loss. You will never be forgotten and I wish you could live longer to enjoy your life. I am so sad that this happened.’
