Comment by Hana on Bad Thinking Diary - Chapter 35

The person she was texting that time was heyra they had something before it's obvious that's why she was the only one who knew Yuna's crush  (minji) she also said in chapter 11 "it's been a long time since u hit me up first" and "my yuna wants to anger me" notice she always try's to hurt minji and not yuna cuz she still got feelings for yunaand can't let go
