Soojin posted in response to the rumors of bullying against her.

Hello, this is Soojin. I'm writing after thinking about this a lot. When I was a student, I always stood out and it's true that bad rumors always followed me around. I did dress unfitting for a student and it's true that I tried out cigarettes a few times as well.
I had my problems when I was young, but I haven't smoked since then. I believe that even though I tried to fix myself, there are things that I did that are embarassing and that I should be sorry for, and that's why this happened. 
But I do have things that I want to say. I always let bad rumors pass, but I want to say something because my fans are haivng such a hard time.
I don't know if you'll believe me, but I'll write things as I remember them. 
I thought that I was friends with the person that posted today. I ate at her house and I even remember watching a movie with her and her older sister. The older sister that gave me advice about reporting to the police when I was receiving threatening messages from a school upperclassman, I've always been thankful to her.
I learned why she wanted to put a distance between us through that post. I remember that we fought because she broke our promise. It wasn't just once or twice and I remember being angry. I didn't know she was trying to put distance between us. So I'm embarassed, but I remember cursing her out as well. And her sister picked up the phone and scolded me. I apologized to her and hung up on her. After that, we became completely apart and had bad feelings toward each other.
But I want to clarify a few things.
First, I never used violence on her. Second, I never rode on a motorcycle. Third, I never sent a group text to bully someone. Fourth, I never stole anything, including her school uniform. Fifth, I never even talked to Seo Sin Ae. I'm sorry because I feel like this also hurt her.
I really don't remember anything about the juice incident. But I believe that I wouldn't do something like that.
I'm sorry that my personal life became a source of a problem, and I apologize to everyone who was hurt by my embarassing actions.

The poster's sister, however, wrote, in a comment that said that it looked like they'll post more since Soojin denied things, "Yes, we'll be writing. Since she can't remember."
