Recently, a situation involving OnlyOneOf’s KB has become a topic of discussion.

Like many other idols, KB is active on TikTok, where he holds livestreams. During the live streams, viewers are able to give gifts through TikTok, resulting in animations on screen.
@inchthewormTHE FILTERS LMAO #onlyoneof #onlyoneofkb #kyubin #kpopfyp
According to fans, the large amount of gifts a particular user gave resulted in them forming a close relationship with KB, in which the idol reportedly shared personal information.
Fans also alleged that this particular fan, reportedly known to have engaged in stalking behavior over the years, used this contact to tell the idol to block fans on TikTok. After an alleged disagreement with KB over another fan and him supposedly blocking her, the fan allegedly exposed private messages between them and the idol.

The fan’s claims eventually resulted in KB issuing a message on his TikTok account, giving his side of the story. He defended himself, claiming the blocked fans were blocked because they participated in a boycott of the group’s recent US tour.
He apologized, calling himself a “victim” of the fan’s alleged manipulation.
@kowabooongaEng) For many years she has claimed she has been bullied by lyons. At events she has told me for a very long time that she has to stop being an OnlyOneOf fan because lyons are bullying her. Aside from her, I have also been informed of fans being bullied, wanting to commit s*icide, leaving our fandom and more. I have received many reports. This is why I asked her for more information so I can know how to help and protect lyons. I trusted her because I thought she was a lyon who wanted to help other lyons. I was blocking people who hated/boycotted our concert, and bullied other fans because I felt I had the duty to protect lyons. She would constantly get angry at me and say that my actions were ruining the fandom, she tried to manipulate and control my actions, and wanted to have all my attention. Because of this I have been extremely stressed for a little bit now, so I asked my manager to communicate this with her. She created fake messages, and made up lies about messaged I sent in order to fit her narrative. Fake accounts have been getting created and going after my fans. Myself and my fans have recently received death threats, and have been told to kill ourselves. I have been told by these fake accounts to stop going live or else my fans, and my safety would be threatened. I want you all to know that she has not been telling the truth and I have all the evidence and witnesses necessary to show she is behind these fake accounts and the lies she spreads. The amount of money I have made or been gifted from these lives does not matter. Many people have given me gifts and I appreciate them greatly, but I will always love all lyons equally even if they cannot gift me. I want to ask you all for forgiveness for what I have done, my goal was to always protect lyons but I fell victim to her. I am sorry to everyone who has been affected or disappointed by these recent events. I want to make it clear that she, who is still harassing fans, is not telling the truth. People close to her who watched her actions have become my witnesses because they no longer supported what she was doing. Please do not believe this liar, do not be misled, and do not give her attention. The victims of her actions are suffering, they message me telling me they can’t eat or they can’t sleep because of the pain. Please do not believe anything she says. Once again I want to sincerely apologize to anyone who I have hurt or disappointed because of this situation. I am sorry. ————————————- 한국어) 그녀는 자기가 괴롭힘을 당하는 라이온이라고 몇년째 주장했습니다. 팬사인회에서도 오랫동안 저에게 자신이 팬덤에게서 괴롭힘을 당해서 온리원오브를 떠나야한다고 말했습니다. 저 또한 오래전 부터 괴롭힘을 당해서 떠나고, 자살하고싶다고 말하는 팬들이 있다고 들었고 여러가지 증거들도 보았고 제보도 많이 받아왔습니다. 그렇기에 저는 그녀에게 더욱 자세한 정보와 내가 무엇을 해야 라이온을 지킬 수 있는지 물어보았습니다. 그녀가 라이온을 위한다고 생각하고 그녀를 신뢰했었습니다. lyon들을 보호해야한다는 생각에 콘서트를 방해하고 다른 팬들을 괴롭힌다는 사람들을 차단도 하고 그들을 위해 목소리를 내었습니다. 그녀는 지속적으로 저의 행동이 팬덤을 망가뜨린다며 화를내고 저의 행동을 조종하고 원하는 답을 하도록 유도하고, 세뇌시키며 저의 관심을 차지하려고 했습니다. 극도의 스트레스로 인해 그녀와의 메세지를 에이전시 매니저님께 부탁하여 소통을 하였습니다. 그리고 매니저님은 그녀의 비위를 맞춰주며 증거를 모아갔습니다. 그녀는 가짜 메세지를 만들고 제가 하지도 않은 말을 꾸며 내었고 다른 메세지들은 의도와는 다른 캡션을 달아서 완전히 다른 의미로 보이게끔 만들었습니다 . 심지어 가짜계정을 만들어서 팬들과 저에게 살해협박을 하고 가짜계정이 팬덤을 위협하고 자신의 신변을 위협한다고 라이브를 중단하라고 주장했습니다. 그녀가 가짜계정의 배후라는 증거와 증인도 존재하기때문에 그녀가 진실을 말하지 않고 있다고 말씀 드리고 싶습니다. 돈을 위해서 제가 이런 일을 했다고 하기엔 액수가 중요한 것은 아니겠지만 저에게 더욱 많은 기프트를 준 고마운 사람들이 많습니다. 그리고 제가 그녀에게 받은 액수는 심지어 이글을 보고있는 사람들이 온리원오브를 위해 지불한 돈 보다 적을 수 있습니다. 누구라도 저에게 도움을 요청했다면 노력했을 것입니다. 모두를 사랑하기 때문입니다. 제가 무엇을 위해 그렇게 노력했다고 생각 하시나요🥲 그저 라이온을 지키기 위해서 했던 행동들과 그녀에게 속은 바보같은 저를 용서 해주셨으면 좋겠습니다. 이 일로 인해서 피해를 받았거나 실망하신분들에게 정말 죄송하다는 말씀을 드리고 싶습니다. 그리고 다른 팬들을 괴롭히는것을 멈추지 않는 그녀가 진실을 말하지 않고 있다는 것을 알려주고 싶습니다. 그녀의 행보를 지켜본 그녀의 지인도 더 이상 옳지 않은일이라 생각해서 저의 증인이 되어 주었고, 가짜계정이 아니라고 주장하는 거짓말쟁이를 더이상 믿지 않고, 선동 되지 않고 관심주지 않았으면 하는 부탁을 드리고 싶습니다 지금 이순간에도 피해자들은 밥도 못먹고 잠도 못자며 고통을 받고있습니다. 제발 그녀의 말에 신뢰를 주지 말아주세요. 다시한번 이 일로 저에게 피해를 본 분이나 저에게 실망하신 분이 있다면 사과드리고 싶습니다. 죄송합니다.

Many have chimed in on the situation, with many having sympathy for KB in light of his alleged financial difficulties leaving him open to manipulation.
i think everyone is underestimating how genuinely poor kyubin is, he literally has no money 😭 when you're this broke you'll do anything for a cheque, if blocking a few fans meant money i'd do it too if i was desperate. i think we need to give him some grace here pic.twitter.com/WQTW2LcGqo

victim blaming kyubin for being taken advantage of and essentially blackmailed is extremely gross behavior
if you lack that much basic empathy and have no ability to understand what he was going through behind closed doors, I'm concerned for you

On the other hand, many feel as though this has “ended” the group, especially considering that KB blocked fans who boycotted out of hopes of protecting the group from mistreatment at the hands of a tour management company. Others felt that Kyubin should had firmer boundaries in his interactions, which might have helped avoid this situation.
The boycotting part is pissing me off so bad considering fans boycotted for ooo’s safety. This is just unfair on lyons https://t.co/O888hmWEfQ

ok well onlyoneof is 6ft under now can't wait for rie to get back from the military to an empty dorm and locks on the company building and for them all to stop being idols and probably go into producing or acting and never talk to each other publicly again pic.twitter.com/qm8QMgZpm4

It’s kind of crazy how some idols enable parasocial shit back. Like this could have been avoided by having firmer boundaries. Idk how to feel about all this tbh. OOO are one of my ult groups but this is kinda insane https://t.co/byS1UjOs4I
