Answer: C. Suzy Nakamura
Suzy Nakamura is the girl that both Wei-Chen and Jin fight over. She is kind and sensitive, and she experiences many of the tribulations that Jin feels. However, she is more outspoken. She also struggles with her race, and often feels like an outsider. However, Suzy's personality is clear from the beginning, and does not change throughout the story. Therefore, she is a flat character.
