Eun-Hyuk Lee

Eighteen year old Hyuk Lee is the leader of the Green Roof Apartments Survivors and Eun Lee's older brother. He is also one of the deuteragonists of the series with the others being some of the Green Roof Apartment survivors.

Hyuk is an intelligent and level-headed young man with an affinity for leadership. He often plans the many missions the survivors need to undertake. He is unafraid to take risks and is pragmatic, such as accepting an infected human into their ranks, if it helps boost their success rates. He also was prepared to take underhanded measures to tip the odds in his favor. However, as other survivors have learned, Hyuk is extremely blunt in speech and often says things rudely or in a way that would draw their ire. Hyuk is aware of this trait and either uses it to energize people or to provoke people for his own enjoyment. Due to his video game playing habits, he occasionally offers explanations using video game terminology. Because of this and his bluntness, it often embarrasses his sister Eun. Despite this, Hyuk deeply cares about Eun. He notices her actions and is able to deduce that Eun has a crush on Hyun. Hyuk also possesses empathetic traits but masks it greatly for both survival and so that no biases are made when it came to decision making as a leader. However, if there is no harm to the survivors, Hyuk would let emotions and morality guide his decisions.
