You're right, I probably DID misunderstand her. But that still doesn't make me like her. To me, a man who is bad at reading social cues/understanding emotions and shit, it just looks like she's bipolar. One second she's kind and caring and the next she's chewing you out for an hour because you breathed wrong or something.
It also doesn't change the fact that she seems more closed off than the others even after her 2nd H-scene. No matter what, you cannot increase your points with her through the basic repeatable hangout events. ONLY through her unique story events. Every other character's points can be increased (infinitely?) through the hangout events with the exception of Zeline before her 2nd or 3rd event. After her 2nd or 3rd Zeline can also have her points increased through repetition.
And even if she IS genuine with Kanoi, I still don't think she's the... best influence on her. No clue if Kanoi has already witnessed Hazel's rage or not, but that's probably not something Kanoi needs nor wants to see. Plus some of the stuff Hazel tells Kanoi isn't too great either. Which I guess Jin can correct, now that he's in Kanoi's "inner circle," but still.
