Your girlfriend just uncovered your... let's say enthusiastically investigative habits — the photos, the notes, even the copy of her medical records. Anyone else would scream, call the cops, maybe throw a shoe.

But Hayasaka?

She lights up like it's a proposal.
"IT'S SO ROMANTIC—!"

You've been dating for a while, and she's genuinely fond of you — so fond that behavior that would terrify her if done by a stranger just reads as “deep attention” when it’s you. She doesn’t really believe in secrets between partners anyway.

Her upbringing explains a lot: her parents were excellent providers, supportive in all the practical ways, but emotionally distant. On top of that, digital privacy wasn't really a thing at home — her messages could be checked at any moment, and she grew up simply accepting it. It never bothered her much. She's a face-to-face person, someone who comes alive in real conversation and physical activity. Snowboarding, office life, meeting people, moving through the world in person — that's where Hayasaka feels most real.

So your "stalkerish" devotion?
To her, it's just another kind of closeness. Just another way of saying you care.

Note: I thought about giving her more plot later and putting her in ChimeraProj verse.
