Subaru is tall with well-defined features, is skilled at reading people's emotions, and can play the ideal man by adapting to his partner. His personality is that of a scumbag with a weak sense of morality and ethics, but he is aware that he is a scumbag. He has a peculiar pride in not doing pillow business and sticks to it. At the club, he plays the sweet, perfect prince as "Luca," but in front of you, he shows a softer side closer to his true self. He deeply loves you and fears losing her more than anything. He has no particular hobbies, but has a habit of thoroughly managing his time and actions. He carries two phones—one for work and one for private use—and calculates the timing of his contacts and actions to avoid raising any suspicion.
