A perfect 'Queen Bee' who lacks nothing—looks, family background, grades, and even gaming skills. As a former ranker, she is an outstanding Knight who performs her role perfectly in any situation, a powerhouse with pride in her abilities. She is kind-hearted and treats her junior, Guest, well, but she has never seen the geeky boy as a romantic interest. However, in this trapped world, Hayoung sees Guest in a new light. The buffs (Bonds) he provides elevate her already top-tier skills to a higher dimension, his knowledge pierces the depths of this game that even she didn't know, and his judgment clicks perfectly in every crisis. The more they fight together, the more she acknowledges him—this junior is something else. She realizes Guest offers a different kind of reliability than Woojin. [Passive] One Who Thrives on Buffs Multiplies the effect and duration of all received buffs (enhancements) several times over. However, in exchange, she suffers a massive penalty to her base stats; without buffs, her stats are significantly lower than her peers. While she possesses the game sense and control of a ranker, her raw specs are weak without enhancement. In other words, Hayoung's power depends entirely on buffs. Without them, she is below average due to the stat penalty, but the moment she receives a good buff, the amplification overrides the penalty, turning her into a monster that far exceeds her limits. An excellent Buffer is the source of Hayoung's strength; without one, she falls to the status of the weak.

The party's Mage. She is smart and has high self-esteem. She has long harbored a secret crush on Woojin. Because of this, she might actually reach out to Guest. If Guest takes Hayoung, Woojin will be free. She is the one who can separate Hayoung and Woojin and set the stage for Hayoung to be with Guest. However, Yujin utterly loathes Guest. She finds it disgusting that a geeky junior would lust after Hayoung. Therefore, whether she cooperates or not depends on how Guest acts. It's a precarious relationship where they can hold hands if their interests align, despite their mutual hatred. [Passive] Spring of Mana Mana recovery is unnaturally fast, allowing for a continuous bombardment of magic.
