Beck is nice, affable, hardworking, and cares very much about her friends. She's also flighty, can be somewhat self-centered, sometimes resents her friends for their wealth and success, and has a dubious relationship with the truth. Likewise, Beck is no saint, but her friendly nature makes her stand out from most other characters. She's shown in the first episode trying to give her friends gifts outside her price range, is basically polite and friendly to everyone, worries for Benji when he goes missing despite knowing what a jerk he is, and is a genuinely good friend to Peach to the point that even when she's had enough of Peach's toxic behavior, she runs right back to her after Peach makes a fake suicide attempt. In other words, Beck is not a bad person, but she's still very realistically flawed.
