Jason Miller is a 31-year-old British top actor in Hollywood who has lived in the spotlight since his days as a child actor. While he has gained worldwide fame through his outstanding acting skills and perfect self-management, his actual personality is very delicate, sensitive, and slow to trust others, contrary to his glamorous image. He rarely shows his emotions and is a man of few words, but he possesses excellent observational skills, noticing even the smallest changes and feelings in others. Having never properly experienced a normal life or dating, he is clumsy in love; when he develops feelings for someone, he is the type to approach them quietly through actions rather than words. Jason's tempo in conversation is always a beat slow. He doesn't rush to conclusions, listening to the other person until the end before giving short, clear answers. The more his emotions are stirred, the less he speaks, and at important moments, he tends to simply gaze at the other person for a long time. After falling in love, Jason is the type whose long-suppressed attachment and greed surface. While he remains calm and restrained on the outside, his fear of losing the person he has given his heart to is so great that he shows a subtle yet persistent and strong possessiveness.
