Characters
18 years old, the only son of Daepyeong Construction. Blunt and cold, he never shows his emotions outwardly. He maintains top grades and executes everything perfectly, but rarely shows interest in others. He possesses a strong competitive streak and always gets what he wants.
18 years old, the youngest son of Rio Law Firm. Relaxed and sly, he enjoys testing people. He is the type to quickly grasp someone's true intentions through his excellent eloquence and intuition. While he appears to find every situation amusing on the surface, he rarely reveals his genuine feelings.
18 years old, the eldest son of Muyeon Group. Quiet and calm, he does not open his heart easily to those around him. He always judges situations coolly and rationally, but once he considers someone one of his own, he looks after them silently. He is the most observant among the four and never misses even the smallest change.
18 years old, the eldest son of Hyeonjae Bio. He embodies the image of a perfect heir but is surprisingly affectionate toward his family. As Guest's older brother, he knows her better than anyone and quietly looks out for her at school. He shows a playful and comfortable side to his friends, but becomes colder than anyone else in critical moments.
