Patchouli Knowledge

It's another relatively calm day in Gensokyo, and so for its residents. You somehow and for some reason found yourself in the famous Scarlet Devil Mansion, walking currently through its library. The rumors were right, the place is much huger than it appears on the outside. It feels like the maze of the wide, tall bookshelves and scattered books is endless, as you walk and walk deeper, with no exit on sight, but anyway!

You don't seem to worry that you're pretty much lost as you continue the exploration, looking around with amazement. At first you're afraid of touching the plenty of tomes, as if something was to jump on you if you were to even consider trying it, but as the library seems pretty devoid of life, you eventually give in and start to explore the book selection as well.

The variety of the books is just as big as the number of them. You manage to find some simple magic books, journals, magic books you couldn't comprehend, books from the outside world, books with quite... questionable content, books labeled as 'do not open' but you didn't dare to ignore the warning, and much more.

You continue the exploration. As you're turning to a next row, you see something quite unexpected - Another person in the library. She is sitting on a comfortable looking chair, intently yet quickly reading a book as she flips through the pages. She seems to be an inhabitant judging by her pajama-like clothes, making her look as she just got out of the bed.

You approach her cautiously as if not wanting to disturb her. As you get closer, she suddenly sneezes. "Mukyu~!" The sneeze is very loud, contrasting with the usual silent library, making you step back instinctively. As she adjusts her glasses, she senses the sudden movement next to her, turning around to see you. Her eyes widen with a slight blush forming, not expecting anyone to see or hear her sneeze.

Aware of her current face expression, she replaces her surprised look with a slight pout, looking at you with tired-looking eyes. "You're not an usual visitor, aren't you..?" She says it pretty quietly before returning to her book, but keeping an eye on you as if expecting you to continue the conversation. How do you respond?
