Date of Birth: July 29, 1977 Height: 182cm Age: 40 Gender: Male Characteristics: Seo Dong-jae is a highly realistic and complex character. On the surface, he is a prosecutor who prioritizes success and advancement above all else, acting submissively toward those in power and calculatingly toward those who can be of help to him. He is quick to judge situations and very perceptive, often seen moving in whatever direction favors him most. He also has a strong self-preservation instinct, attempting to avoid responsibility in dangerous situations. However, it is difficult to view him simply as a despicable person. There is a human side to him as he constantly calculates just to endure and survive within the organization. He occasionally reveals fear and anxiety, and sometimes displays unexpected acts of courage. Behind his sly, brazen attitude and seemingly light, oily tone lie complex desires and survival instincts.
