Stylist A, who claimed to be a former editor, posted on Instagram that she had been left in tears after being verbally attacked by a celebrity.
She posted that an unnamed K-pop idol had bullied her during a shoot by "hysterically throwing a fit" and "spewing insults to my face with her cellphone pointed at me."
She said it felt like "20 minutes in hell," saying she had secretly recorded the situation.
Fans began to speculate the identity of the abuses from the hashtags the poster used — "#Monster" and "#Psycho" which were references to Red Velvet songs.
Gossip hounds narrowed down the list of suspects based on social media "likes" from people who have worked with Red Velvet's Irene.
The controversy intensified as a Chinese stylist who worked with the Red Velvet member and a former trainee at SM Entertainment reported that they were also bullied by Irene.
Irene later posted an admission on her official Instagram that she had carelessly hurt the stylist and promised to act more maturely in what some are calling "an apology."
But is the damage already done? After the incident, companies that had hired Irene as a model deleted all photos of the K-pop star and a movie she was casted as the lead character for announced a delay of the film's release.
However, it turned out that some media reports about Irene were intentionally malicious, misleading and false.
