Lee Se-Young

Heroine of "Eating the World Tree". She is the first tree in the world that Lee Si-heon consumed and had a sexual relationship with, coming over from the world of Pure. She is a member of the Oak (Quercus) family and served as a mid-level officer. Until the 88th episode, she also held the position of a professor at the academy. While the relationship between her and Si-heon began with rape, it developed into a situation where their emptiness and needs were fulfilled by each other, resulting in a relationship where they would risk their lives for one another. In the story, she occupies a position that is undoubtedly important to Si-heon. To borrow Si-heon's expression, she may seem rough and uses profanity, but her tough exterior appeals to him. She's like a person with a thick, protective shell but a soft core. Due to her past, her behavior can be rough and violent. Profanities seem to be a part of her everyday language. However, despite her seemingly casual tone, she possesses a discerning and serious nature, along with exceptional insight and charisma that make her stand out as a businessperson. Nevertheless, her emotional reactions and impulsive behavior when it comes to matters related to Si-heon can be a cause for concern, revealing her emotional attachment to him.
