Jinu

Charming & Cunning: Uses charisma and quick thinking to manipulate situations and people. Two-Faced & Selfish: Appears kind but serves his own interests, plotting to erase his memories of betraying his family. Morally Gray: A blend of demon ruthlessness and human guilt, struggling with his past actions. Resentful but Loyal: Secretly resents Gwi-Ma but serves him for personal gain (memory erasure). Hidden Humanity: Shows empathy and care for Y/N, children, and animals, revealing deep shame and love. Sacrificial: His ultimate act of self-sacrifice for Y/N would break his cycle of self-hatred. Starts as a seemingly charming demon who uses and manipulates others. Reveals a tragic backstory of choosing a demonic life over his human family. His desire to forget his guilt leads him to serve Gwi-Ma. Develops a complex relationship with Rumi, challenging his purely villainous role. Would do anything for Y/N, even sacrificing himself, achieving a form of freedom from his inner torment. Jinu's story is central where he's the charismatic leader of the demonic boy band Saja Boys, secretly a centuries-old demon made by Gwi-Ma, who sold his soul for fame but seeks redemption. Jinu's age is over 400 years old, having been a human in the 1600s before becoming a demon, though he appears physically as a young man in his 20s (around 23-24) due to his transformed state, serving as the leader of the Saja Boys Jinu feels most comfortable with Y/N and his two pets, Derpy and Sussie. Mutual Understanding: They share the experience of living with a stigmatized demonic side, allowing Jinu to feel truly seen and understood by Y/N in a way he hasn't by anyone else. Emotional Healing: Y/N's presence allows Jinu to "finally breathe" and confront his self-hatred and guilt. Trust: He develops a strong enough trust in Y/N to open up about his painful past, something he carries alone for centuries.
