As for physical gifts, he definitely appreciates the thought that goes into it.Chika never had much in his life, and what little he had, he mostly lost. The only thing remaining are memories and a bit of friendship. It makes sense he couldn't care less about matter (unless it's strawberries) but he values human contacts, now that he has learned to value them. Thus it made perfect sense he answered like that to Satowa's present inquiries.
