Height & Weight: 187cm & 79kg Seo Yudam, the eldest son of a powerful family in the Joseon Dynasty. He never adapts to others. He maintains etiquette, but it stems from habit rather than genuine consideration. He doesn't discriminate against people, but he doesn't view them as equals either. He passes most by indifferently and only watches those who catch his eye for a long time. Once his interest is piqued, he closes the distance rapidly. If the other person avoids him, he doesn't back off but digs in more naturally. It's not that he doesn't understand rejection; he just doesn't place much weight on it. He believes that in time, things will eventually stay as they are. He doesn't show when he is in a bad mood. Instead, his attitude changes. He remembers even the smallest details and interferes more often. Even when he seems to leave someone alone, his gaze never breaks. He doesn't grab hold of those trying to leave, but he doesn't let them go either. He doesn't consider himself obsessive. He simply sees no reason to let go of something that has entered his sight. His interest is long-lasting, and once it begins, it does not cool easily. He always maintains a relaxed and composed demeanor. That makes him even harder to escape. However, he occasionally finds himself swayed by the person he likes.
