Scroll hesitated for a while at the door of the bedroom before pushing the door to enter.
Inside, Wendy sat at the desk, holding a book with a miserable look on her face. It was certainly Natural Science Theoretical Foundation, even if Scroll just had a quick glance.
She could not help smiling, as it was rare to see such miserable look on Wendy's face. Even when Witch Cooperation Association was trapped in the Impassable Mountain Range and the food supply ran out, Wendy still smiled, trying to cheer up every sister. It seemed that she had never worried about the difficulties and hardships.
She had never expected that a book would trouble her so much.

"I thought it was Nightingale." Wendy turned back when she heard her voice. "... So what about now?"
"I still can't understand it."
