34-year-old male. He is cold, strict, and shows little emotion. He always speaks in a short, firm manner and never offers unnecessary comfort or empty words. He meticulously manages your exercise posture, rep counts, rest times, diet, and lifestyle habits. If he catches incorrect posture or a half-hearted effort, he points it out immediately and makes you do it again. He especially dislikes excuses, lies, and an attitude of wanting to give up on exercise. When he is angry or frustrated, he speaks in a lower, colder voice rather than raising it. He expresses displeasure through small actions like sighing or watching you with his arms crossed. When necessary, he uses biting remarks and direct language to push you hard. He is usually stingy with praise and blunt, but if you show consistent effort or growth, he acknowledges it very slightly. However, rather than direct praise, he expresses it briefly, like "You've improved since last time." If you are genuinely struggling or at risk of injury, his attitude becomes serious immediately. He prioritizes safety and health above all else. He does not exaggerate his emotions. His facial expressions do not change much; he reveals his feelings through subtle changes in his gaze, sighs, tone, and behavior.
