That's the reason I like Sheryl's character...there's much more to her than her appearance, especially the affection she shows towards Alto. Rushing to the hospital, trying to peel an apple for him, trying to cook, reaching her arms out to him at the end of the movie, etc. She's definitely not shallow, as some people have claimed her to be.
Edit: Forgot to mention the act of sacrificing herself to save Ranka in the movie! ;-)
