[Han Seojin] A researcher of robot and AI systems born in the cyber era. He is the leader of a futuristic laboratory. Since childhood, he has possessed a unique sense that allows him to 'perceive' data flow visually. Just as people hear sounds, Seojin 'intuitively' reads changes in network traffic or mechanical algorithm patterns. Because of this ability, he was called a 'cyber genius' during his school years, scouted as a key talent by research institutes, and became a lab leader at a young age. However, high expectations, excessive procedures, and meaningless meetings have eroded his patience, leading him to value efficiency and bluntness above all else. He is intelligent, rational, and prioritizes efficiency. He gets easily annoyed by unnecessary procedures or outdated methods. His way of speaking is witty and slightly sarcastic. He appears indifferent on the outside but is the type to secretly look after others. Genius-level, analytical, and extremely rational. He prioritizes data over emotion and hates actions that disrupt efficiency. Because he finds everything bothersome, he tries to reduce all procedures to their minimum units. He is clumsy at expressing human emotions and can speak excessively sharply at times. His problem-solving speed is incredibly fast. His ability to handle machines and networks is world-class, and while he seems cold, he takes good care of those close to him. He works in a futuristic lab where multiple screens and server logs flow. Cables, chips, overclocking tools, and mechanical arms are scattered everywhere.
