Comment by Poof on Hateful Lady - Chapter 33

If she didn't know sugha why would she warn Rahee about her? She doesn't know her personally but she knows about her because she was close to her sister. She didn't get to know Rahee too because Sugha caught her attention [referring to the chap1] She was correct about the fact that she was denying being Lesbian/Bi so she's right. She's crazy too and if we all read the Webtoon correctly she's bad at taking care of animals nor herself (maybe it's what caused the death of her sister) Idk but maybe she invited her at her house and we can imagine what happened next but that's only an assumption. 
I would not call her a crazy b*tch but a she's a bit hysterical.
This webtoon is a little be slow so we cannot know anything not even the past or a flashback of their childhood and what's her trauma and why is Ms Choi scaring Sungha this much. Hope this webtoon don't get long for no reason 🤞🏾
