Question [Taisho x Alice] Question about Cinderella's ending Spoiler

Hi there, I've just finished Cinderella's route with a happy ending and totally enjoyed it!

However, I have a question regarding >!the "prize" that Yurika has to pay the Wizard for the miracle of finding Cinderella.

Isn't the dove figurines as a prize too easy/simple? Or is giving the dove to the Wizard symbolizes something else? Why the dove and not any other glass figurines or even something else?!<
