The document provides costume notes for three characters - Jason Steele, Mr. Black, and Mr. White. Jason Steele's costume of a white shirt, red tie, and black coat is described as portraying both sides of his personality and emphasizing his professionalism as part of a secret agency. Mr. Black's patchwork jacket, dark jeans, and earring are meant to signify his unprofessional and casual role as a hitman hired by a gang. Mr. White's blue jeans, black coat, converse sneakers, and glasses are intended to show him as calm but unsuited for the role of a hitman due to his vulnerability and lack of care for his appearance.
