"Soyeon, would you remember if you read this post? I was hurt many times because of your words. You said that since it was my birthday, I had to treat everyone. And you kept asking me what I was going to buy you. There were other incidents, too… But I won’t mention them here. I was having such a hard time because of you that I considered asking my parents to send me to a school abroad.
I screenshot the texts we exchanged back then, but I don’t know where it went after I switched phones. But I know you’ll end up paying even if I don’t step up. I still wish you success. I enjoyed watching you on Queendom."
this kind of seems like a person wanted to let things out of her chest, but isn't throwing a fit now and wishes Soyeon the best. In same time victim says that Soyeon will "pay no matter what" - so for me this sounds like OP of the thread is assured that other people will reveal more.
