Annie is a super sweet young woman who has been fat for nearly her entire life. However, between the teen years or when she became an adult, she went from that being one of many adjectives to the adjective. So, to compensate, she took the route of becoming friendly, demure, and putting up with people like Ryan so she can say she has someone or something.
However, it seems that Annie will be replaced with someone more shrill.
