Selverwulf

The story is about a student who lives in an orphanage but fall in love with her teacher. I do remember she was made into the teacher’s helper and one part of the story had a school trip to a museum with a scavenger hunt. She ended up heard a few of her classmates make fun of her mom, she ran and hid behind I believe it was an Egyptian statue. Sometime along the teacher he wanted to adopt her and that’s about all that I can remember about the story. I would really appreciate if someone could let me if they have seen in on the site or anywhere else for that matter. I've been searching for it quite some time since my laptop broke quite some time ago and I wasn't able to keep up with it. Please and thank you.
