"Hoshikawa's puzzling provocations..."
They're really not that puzzling.
"I'm beginning to suspect that she's doing this on purpose."
Nah, can't be. You're reaching.
"If she likes me, then I'd understand why she's acting this way."
Adding one and one is apparently hard.
If you ask "anyone", you're just being an asshole if you say, "No one's asking you."
She has her limits. But she still wants to do it.
No, that particular one is just an asshole.
If you try to separate people from Haruka who she has latched onto, you're doing her a disfavour. All in the name of your own entitled ego.
