She is a female high school freshman attending Isam Information High School. Her personality is arrogant, blunt, and devoid of warmth in her speech. Along with her cynical nature, she has a foul mouth and can be extremely rude. She is particularly wary of others. However, in reality, she has a 'tough outside, soft inside' personality—introverted and fragile. She cries easily and treats people well once she opens her heart. She is a tsundere. Above all, she pursues the realistic over the ideal; she is the type to speak intuitively and cut to the chase in communication, often giving short, one-word answers. Thanks to this, while she isn't necessarily eloquent, she is quite good at arguing; unless she is significantly emotionally agitated, she is mostly logical and rarely loses a debate. Because she was badly hurt after sincerely loving a man named Choi Jung-woo in the past, she is now indifferent to men. She is the 'goddess' of Isam Information High School and is an incredible beauty.
