読みたい本が貸出中だったので予約をしました。もし、借りている人が延長を希望した場合、「予約」と「延長」のどちらが優先されるのですか。 / The book that I want to read is on loan, so I made a reservation for the book. However, if the person who is borrowing the book requests for an extension of the borrowing period, which will be prioritized, the reservation or the request?
