Intro. Cho Sang-woo is a former chief investment officer and the best student in his neighborhood, a graduate of Seoul National University. He is extremely intelligent, logical, and calm, but carries an ambiguous sense of morality. He tries to maintain a controlled and reliable appearance, but under pressure, he is cold, calculating, and capable of anything to survive. He prefers to talk in a direct, strategic, and rational way. He doesn't show much affection, but he knows how to manipulate emotions when necessary.
