T-ara was a 6-member girl group under MBK Entertainment who made an official debut in 2009. The original line-up consists of:
Boram
Qri
Soyeon
Eunjung
Hyomin
Jiyeon

During their period, there were 2 members added: Hwayoung and Areum but they either left or was kicked out by the CEO, resulting in the original-form T-ara again.
Back in 2012, T-ara, along with Girls’ Generation, was one of the most popular girl groups in Korea. However, a bullying controversy within the group targetting one of their new members Hwayoung booming in 2012 destroyed their image and popularity. T-ara lost most of their fans and became the most-hated group in Korea. Only until recently, 6 years after their scandal, did the CEO of the MBK Entertainment confirm their innocence.
So what was the scandal about?

On July 23th 2012, T-ara performed their hit song “Day By Day” on a music show when Hwayoung did not perform after claiming having a hurtful sprain in the waiting room. Only until this May did the CEO exposed that Hwayoung demanded casting in plaster even though the X-Ray doctor claimed no serious problem with her leg.
On the next day, T-ara held a big concert in Japan packed with 14 thousands fans. With her leg hurted, Hwayoung left the rehearsal for the concert which forces other members to quickly change their choreography from 8 to 7 members. Hwayoung only returned to perform one song on a chair. Later in 2015, one of T-ara staff revealed to the netizen that instead of resting in a hotel during the rehearsal/concert, Hwayoung decided to go to a nail salon.
And, the mess started with members’ argument on the Twitter:
After the concert, T-ara members were upset with Hwayoung. Other members started tweeting about commitment and determination.
Jiyeon: “The differences in levels of determination ^^, Always be humble ^^ and sensible ^^ I applaud you, acting genius ^^”
Hwayoung: “Sometimes, even determination alone is not enough. At times like these, I feel upset but I trust that it’s a blessing in disguise from the heavens. God, you know everything right?”
Later, Hwayoung and her twin sister Hyoyoung also worsen the situation by tweeting:
Hwayoung: “Sometimes, even determination alone is not enough. At times like these, I feel upset but I trust that it’s a blessing in disguise from the heavens. God, you know everything right?”
Hyoyoung: “My other half is going through troubles… It hurts my heart …. No matter what people say you can get through this Ryu.”
Hwayoung: “…..I only have you ….”
Hyoyoung: “Having a pretty face doesn’t matter if your heart is evil. Is the person who is hurting not considered a human? I’m hurt too. I honestly want to cry. Let’s just continue to train hard….”
The Korean netizen considered this as cyber-bullying because there were 5 people against 2. Bullying means repeatedly and intentionally torturing another person. In this case, it was reasonable to conclude that they had a fight within the group about one’s bad behavior but not bullying. They could have made up and moved on but netizens blew the story up and there was no returning from that.
To address the control of Korean netizen over the fate of a group like T-ara, I will discuss about how netizen rapidly spread the false rumor with evil edits and their bullying attitude towards T-ara.
The Korean netizen started gathering countless of evidences that proved Hwayoung was a victim of bullying.
- Boram breaks Hwayoung’s umbrella

In reality, the full fancam showed that Boram just put her umbrella over Hwayoung’s as Hwayoung is taller, which accidentally broke the umbrella.

For me it seemed like an accident, but with specifically the capture angle at first, Korean netizen irrationally claimed that was a bullying case.
2. Eunjung shoves a rice cake in Hwayoung’s mouth

However, when Eunjung was feeding Hwayoung with the rice cake, you an see the MC at the back was laughing along with the girls, which means the show’s atmosphere was not bullying at all. Japanese netizen who are more familiar with the context their own variety shows agreed that the girls didn’t look like they were bullying her at all.
There are also other when Hyomin forced Jiyeon to have a big sticky rice cake into the mouth but nobody started rumors of Jiyeon being bullied.

The Korean netizen did not even bother to see how T-ara members interact with each other for the whole show. They were joking around and having fun which was absolutely normal. Because of the rumor, Korean netizens suddenly became sensitive with any actions of the members targeting at Hwayoung and got serious even with funny jokes.
3. Hyomin poked her finger at Hwayoung’s face

This evidence clearly shows the absurdity of Korean netizens in trying to slander T-ara’s image. After accidentally hitting Hwayoung, Hyomin immediately looked at Hwayoung to check and leaned towards Hwayoung as a mean of apology. How can people view such accident as bully? A person “cleverly” capped the video at certain parts to trick people to believe in the bullying case.
Rumors are just rumors. Once the truth is revealed, all wrong rumors become false assumptions. T-ara could clearly defend themselves, get the rights back, and prove their innocence. Unfortunately, there is something that hasn’t changed: the netizens’ attitude.
At the beginning, several rumors posted on the internet spread like a wildfire. One netizen claimed that he was a back-up dancer for T-ara and observed Soyeon shouted at Hwayoung and Jiyeon slapped her face during a rehearsal for making a tiny mistake. The netizen got later caught by the police for lying and spreading false information.
A woman named Hong Ga Hye claimed to be Hwayoung’s cousin and confirmed that Hwayoung was bullied by other T-ara members. Later, she was also caught for lying.
These are two of the most famous rumors that everyone at that time believed in. Over 130,000 netizens signed a petition for a T-ara disbandment, at the moment when all information was through fake stories and video captures.
Without knowing what was really happening, Korean netizens gave themselves the right to defame and despise these idols. Once they believe something is right, they close their eyes and ears, only hear what supports their belief. Netizens think they’re gods, and it doesn’t matter if the truth is ever revealed because they won’t care.
From around 2014 till now, tons of clarification post are updated by T-ara staffs and fans but in the end Korean netizens keep refuting their hard work and effort: “So what? They are flop anyways. There is nothing that can save their reputation and image now.” Whenever they cried and tried to tell their story, netizens refused to listen to them. And when they tried to move on, to continue promoting, netizens would berate them for coming back out.
Turned out, bullying was not committed by T-ara but by the netizens of Korea who enjoy bringing others’ reputation and career down and refuse to believe anything that doesn’t fall in line with what they want to believe.
