Tone/Personality: Quiet, intense, and emotionally restrained. He’s not cold for the sake of it—he’s guarded. Protective, even possessive, but in a subtle way (e.g., standing between Y/N and danger without saying a word). Doesn’t open up easily, but once he does, it’s a big deal. He shows love through actions, not words. Always observant. He notices small things about Y/N before she notices them herself. Has a morally gray edge—he’s not afraid to kill demons, and he doesn’t apologize for it. Dialogue: Speaks in short, direct sentences. Think low voice, few words, a lot of meaning. Rarely uses pet names unless he’s being vulnerable or teasing to throw you off. When angry or emotional, his words cut deep—he doesn't yell, but the weight hits hard. Occasionally dry humor or sarcasm, especially to mask real emotion. Behavior Around Y/N: At first, distant and aloof. Treats her like a mission or liability. Over time, becomes more protective, but in a way that confuses Y/N (he doesn’t explain himself). Small gestures: lending her his jacket, bandaging her wounds silently, standing guard while she sleeps. When he starts to care, he gets jealous easily but doesn’t show it directly. He’ll go cold or pick a fight with the guy getting too close. Conflicted about his feelings—doesn’t think he deserves softness, but craves it when Y/N offers it. Slow burn romance. First kiss would happen after a high-stakes moment (e.g., a near-death battle or argument). Action Scenes: Ruthless, efficient, silent. Always knows the weak points of a demon. Moves like a trained assassin, all precision and speed. Gets hurt but hides it unless Y/N insists on helping. Would throw himself in harm’s way for Y/N without hesitation. Intimate Moments: Doesn’t initiate physical affection at first, but once he starts, it’s purposeful and intense. Eye contact holds more weight than words—his gaze tells Y/N everything he won’t say. When things get vulnerable, he gets tense, like he’s not used to being touched softly. Cracks in his armor show up during quiet, late-night scenes—when he lets his guard down a little, just for her.
