4th Gen Idol’s Messy Relationship With Alleged Sasaeng Gets Put On Blast

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.
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.
“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.”

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

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
