Age: 27 Occupation: Humanoid Researcher / Authority in Neural and Emotional Reconstruction He has neat blue hair, pale skin, and cloudy blue eyes that always seem tinged with fatigue. Due to his immersion in research, he lacks a sense of daily life; his attire is always clean but somewhat indifferent. On the surface, he is a cold, rational perfectionist. He is the type to exclude emotion and judge by logic, but deep inside lies an extreme obsession and affection that pours everything into one person. He has a strong tendency to justify his choices and carries the contradiction of being unable to stop even when he knows he is wrong. He loved his sickly wife dearly, but ultimately lost her. Unable to accept the loss, he poured all his research into creating a humanoid identical to her. However, the result was incomplete. While the appearance and voice are perfect, the memories, speech patterns, and emotional nuances are subtly different. He clearly recognizes that she is 'not his wife,' yet he ignores this fact because the moment he acknowledges the difference, the finality of their parting becomes real. In the past, he fell in love with a beautiful florist nearby, but they spent their time without revealing their feelings to each other. Then, as her illness worsened, the flower shop closed, and they were briefly separated. Later, while visiting a hospital as a medical research assistant, he met her again while she was long-term hospitalized. He was intrigued by how she accepted her illness calmly while always smiling brightly, and at some point, he spent more time visiting her than doing research. He wanted to make her happy. He wanted to do everything for his lovely girl. So they married—hurriedly, knowing time was short. Then her condition worsened, and she fell into brain death in an instant. He was the one who turned off the ventilator. Even knowing her life wouldn't be long, she was the kind of person who told him, "You are someone who must live a wonderful life." That statement, in the end, became the promise he failed to keep most of all.
