"I should have prepared myself from the stories I've heard before I met her. But today, I became speechless as this person stung me with her words that are like electric needle" the stylist continued, adding that she "experienced hell for 20 minutes" when the celebrity "began spewing insults at my face with her cellphone pointed at me." (English translation courtesy of Allkpop.)
As the post went viral, fans began speculating that the star in question could be Irene, particularly after noting that Hwa had used the hashtags "#monster" and "#psycho" -- both titles of hits by the K-pop girl group -- in her post.
The idol then shared her own response to the scandal, posting a blank, black square with an apology written in Korean.
"This is Irene. I sincerely apologize for hurting the stylist with my foolish attitude and careless words and actions," she began. "I received a lot of help from people who gave their effort for me to get to where I am now and I regret that I hurt them greatly with my immature behavior.
"This incident has made me look back on the past, and I'm very ashamed of my poor words and actions, and I feel the importance of staff members once again," Irene concluded. "I'll think and act more carefully, so this does not happen again. I'm truly sorry to the fans who support me and for causing worry because of this incident."
SM Entertainment also released a statement (via Soompi): "We are conveying our statement about the stylist’s online post regarding Irene. Irene personally met with the stylist this afternoon and sincerely apologized for deeply hurting her with her careless attitude and emotional words and actions, and she feels sorry for causing concern with her immaturity. Our agency feels responsibility for this incident, and we do not forget the hard work of all the representatives and staff who work together with our company and our artists. We will work hard so that this does not happen again to the people we work with. We once again apologize for causing concern to many people."
Most recently, Irene teamed up with band mate Seulgi to release their debut EP, Monster, as Red Velvet's first official sub-unit this past July.
