what's funniest about the people talking shit about Hebikawa--
Is that up to now, she's actually not done anything to Kusunoki, other than decide that she "wanted to see Kusunoki's darkness". But the (relatively few) times she's actually interacted with Kusunoki, she's not done or said anything to her specifically that could be considered "bad". She teased Kusunoki a little about whether she had a crush on Keisuke (which is when she first clued in that Kusunoki might have some subconscious feelings that she could weaponize)--and she talked shit about Irie during the Festival Play, wherein Kusunoki defended Irie, said some heartfelt stuff toward Hebikawa, and Hebikawa got mad on her own about how it seemed like Kusunoki was 'judging her' (and it was entirely her own read of the interaction, after-the-fact).
Like, she's done actual fuck-all toward the FL, and while she is determined to "use" Keisuke to get to Kusunoki, she's instead started falling for him bit by bit as he continues being authentic around her and not letting her play the "fake act" she's gotten down pat. And even her "bullying" that we've seen toward others, past and present, was a reaction to being bullied herself, and then badmouthing people in "polite ways" to turn others against them.
You'd think she'd killed Kusunoki's cat, the way some people talk about her, but in truth she's actually been very ineffective toward the FL this entire time, only reiterating her desire to "unmask" Kusunoki, but making no actual progress (and finding herself slowly changing, to boot).
Just entertaining how much hate she gets from those who dislike her, and how disproportionate it seems the moment you actually read the story.
