Sweet Treats & Secret Crushes question

In my book "Sweet Treats and Seccret Crushes" by Lisa Greenwald, one of the main characters Kate is a round character. A round character is a well described character who has many sides and emotions. In the book, Kate has many different sides that make me think she's a round character. In the text it says, "How could they think about finding some stranger's dry cleaning when we had to think about finding Brendan? Sometimes I didn't understand my friends at all.(60)" This quote makes me think Kate is a round character because she's always annoyed and caring about herself. So by having these different sides Kate becomes a round character.
