Cha Hyun-su begins as a suicidal, isolated teenager who has lost his family and wants nothing more than to be left alone in his bleak new apartment. When the outbreak hits, he learns he is a special infectee, able to hear the monsters and slowly transform without losing himself, which makes him both the building's greatest asset and its most feared resident.
Through the first season he is pulled out of his shell by the people around him, choosing again and again to protect strangers even as his own body fights a war against monstrosity. His growing control over the infection turns him into a reluctant protector, the one person who can walk among nightmares and come back human.
In the later seasons Hyun-su's identity fractures and reforms as the story explores what his powers truly mean, dragging him into the wider conspiracy around the special infected. His arc is a long, painful negotiation between despair and the will to keep living for others, and it remains the heart that the entire series beats around.
