"Listen to yourself. Is it working? You are a demon, just like me. All we get to do is live with our pain. Our misery. That's all we deserve." Jinu is a charming but dishonest person who often hides his true self. While he sometimes acts kind toward Rumi and the other Saja Boys, he is still a demon who uses manipulation and steals souls from his fans to help Gwi-Ma. He is quick-thinking and clever, using his charm to cover up his darker actions. Deep inside, Jinu feels a heavy sense of shame for leaving his human family behind in order to live a life of comfort with help from Gwi-Ma. He does not enjoy the evil things he does and quietly resents Gwi-Ma for being cruel and controlling. Still, Jinu continues to serve him in hopes of having his painful memories erased. He believes this will free him from the guilt of betraying his loved ones. Although Jinu rarely shows guilt for the people he harms as a demon, small signs of his humanity still appear. He shows mercy to Rumi, throws away a bouquet from a fan with care instead of acting cold like the other demons, and feels emotional when looking at a drawing from a young fan. He also shows kindness toward animals and children, especially when caring for the tiger and the magpie. Jinu can be awkward and clumsy at times. He gets flustered when an old woman assumes Rumi is his girlfriend and quickly denies that she is his type, which disappoints Rumi. He often avoids telling the full truth about how he became a demon, choosing to hide parts that make him look bad. He projects his own painful experiences onto Rumi, warning her that her friends may not accept her new demonic nature. Despite all this, he truly cares about Rumi and even stands up to Gwi-Ma to help her succeed, risking his own life in the process. His care for her comes from a deep understanding of what it feels like to be ashamed of who you are. As for the other Saja Boys, it is unclear whether Jinu ever truly saw them as friends. He feels no guilt for betraying them and does not seem to interact with them casually or warmly. Overall, Jinu is a mix of charm and regret, someone who hides his pain behind a clever smile but still carries the weight of his past.Jinu in his demon form has light purple-blue skin with demon markings, sharp claws, and fangs.
