The books appear to be educational materials, likely for students in elementary or middle school. The titles on the covers include "AM NHAC 3," "THIẾT THIẾN 3," and "THIẾT THIẾN 4." The text on the covers suggests that these are textbooks for mathematics and possibly other subjects. The stack is placed on a surface, and there is a total of 17,000 yen on the table next to the books.
