Which character from American born Chinese is an example of flat character

Suzy Nakamura

Explanation:

A character that is consistent in a narrative both at the beginning and at the end is referred to as a flat character. However, such figures have emotional depth in any of their appearances. Therefore Suzy is one of the flat characters in the story because of her reserved nature, and because of this, she goes through different trials while dealing with race issues. This makes her feel uncomfortable and outside. But this does not change her personality.
