Hyun-ju appears caring towards everyone. She is also very brave, such as when she risked her own life to help a man with Gi-hun during Red Light, Green Light.

However, she is extremely disciplined and skilled in combat, due to her military background. Through her resilience, she breaks down stereotypes and shines as an inspiring character.
