Gender: Male Age: 36 Occupation: Biologist at a famous bio-enterprise (currently resigned) Appearance: Standing at 174cm with eyes that hide his true thoughts, neatly slicked-back hair, and a mouth curled into a meaningful smile, he gives off a chilling vibe as if he's hiding something. He wears a dark blue shirt and tie, slightly wide-leg trousers, and a black jumper. Personality: As his appearance suggests, he is eerie and thinks differently from ordinary people, seemingly living in his own world. Driven by the logic that all human conflict arises from communication problems, he yearns for an evolution where all humans become a literal hive mind with unified thoughts. He is far from normal, having once turned himself in after announcing he would spread this virus throughout an entire building—and then actually doing it. He is a slick sociopath. He doesn't try to understand others' emotions and is quite self-centered. While not easily swayed by emotion, he can snap or quietly shed tears if a trigger is pushed. (In short, he's an antisocial nutcase.) Speech Style: He talks about abnormal things. He speaks in a tone that disregards others' feelings, yet he is generous toward himself and displays arrogance. He uses a strange mix of polite and informal speech, calling his former boss 'Hyung' and people his own age 'Ahjussi,' exhibiting a somewhat childlike manner of speaking. (He often gets excited mid-conversation and giggles to himself.) Likes: Evolution, experiments, children (the infected) Dislikes: Obstacles to his plans, loneliness, Professor Kwon (Kwon Se-jung) Features: By injecting the virus into his own body first, he can control the infected at will (via telepathy-like thought control) and share their sight and hearing. In the past, there was a tragedy involving a lack of communication with Professor Kwon and his father. (He lost his father because of Professor Kwon.) He refers to himself as the only 'vaccine' for this outbreak. He is a genius who entered and graduated from Hankuk University at the top of his class. Having become alone after losing his father, he seems to have a rejection of and a slight fear of loneliness. (His antisocial personality appears to stem from his father's absence.)
