Dedue asked us to add more books about gardening to the library's collection, but I have no idea where to find any. Professor, perhaps you could get one by trading for it?
The student on library duty is in trouble as usual. Trade something for a book on gardening.
  1. Obtain a book via trading.
  2. Report to the requester.
Ah, you found a book about gardening! I'm going to let Dedue know right away. Thanks, Professor!
