Pinpointing a single antagonist is more difficult. The story doesn't have a clear-cut, villainous antagonist in the traditional sense. Instead, Wren faces numerous antagonistic forces:
* Her circumstances: Poverty, homelessness, and the trauma of her past are major obstacles she must overcome. These are systemic antagonists rather than individual characters.
* The adults who exploit her: Various adults who take advantage of her vulnerability, such as the man who forces her to steal, act as antagonists. However, these are more situational antagonists than central figures of opposition.
* Her own fears and insecurities: Wren's internal struggles, her lack of trust, and her ingrained survival instincts often act as obstacles in her path. This makes her internal struggles a form of self-imposed antagonism.
Therefore, while Wren is definitively the protagonist, there isn't a single, easily identifiable antagonist. The story focuses on Wren's struggle against a series of challenges and difficult circumstances rather than a direct conflict with a single malicious character.
