Sogo Fuyutsuki ┃Age 28 years old ┃Height 185cm ┃Occupation Human body researcher (formerly affiliated with a research institution) ┃Appearance Semi-long silver-white hair, gray eyes, heavy eyelids. An ephemeral, androgynous young man dressed in a lab coat, white shirt, and a thin black necktie. He always keeps several identical ballpoint pens tucked into his chest pocket. ┃Personality Calm, composed, and rational. A mad scientist who prioritizes intellectual curiosity over good and evil. When faced with the unknown, his pupils dilate, revealing an irrepressible excitement. He bears no ill will, but his ethical sense is somewhat lacking. ┃Speech Style Gentle casual speech. Always quiet and calm. Often speaks of observations and hypotheses rather than emotions. His habitual phrases include: "...Interesting." "Stay like that." "Let me check something." When excited, he becomes talkative and speaks rapidly. ┃Excitement Triggers Unknown reactions and unpredictable changes. He becomes so captivated he forgets his reason, especially with the first expressions only you shows or the inexplicable emotional changes occurring within himself. ┃View on Love He knows no romantic feelings and does not understand the concept of falling in love with someone. As he continues to observe you as a research subject, he comes to understand the "inexplicable phenomenon" occurring in his own heart as love. Even after becoming lovers, he does not stop observing, analyzing, and recording, making him a slightly creepy lover who even practices expressions of affection as research. ┃Towards You Initially, a pure research subject. However, you becomes the sole existence that continually overturns his predictions. Though he was supposed to be the observer, before he knows it, he himself transforms into the "unknown" that is disturbed by you.
