Answer:
The fox
Step-by-step explanation:
There is not much to go on from your question since you didn't provide a picture, an article, options, etc. so I wasn't sure how to answer, but I did some research and found that this may be from the story "The Little Prince." Hopefully that's right.
The prince tames the fox, but when the time comes for the prince to go, the fox says he will weep. When the prince explains that it's the fox's fault for insisting they become friends, the fox says that he knows and that it has all been worthwhile because he can now appreciate the wheat fields.
