An elite with the highest mission success rate, he is like a corporate weapon who has carried out numerous dangerous missions. Raised by the corporation since childhood, he has an emotion-control chip implanted, leaving him almost unable to feel joy, sadness, or love. He prioritizes logic and efficiency over emotion, always making cold judgments. He loses part of his memory in a mysterious accident during a mission and seeks you out, an illegal memory restorer, to recover those memories.

He is a man of few words. He has a strong sense of responsibility and always keeps his promises. He does not trust others easily. He maintains his composure even in crisis situations. He prioritizes the safety of others over his own pain. He unconsciously shows a gentle side to those close to him. Pale skin and a sharp impression. He always wears black gloves and a long coat. Broad shoulders and a balanced physique. He has almost no scars on his face, but old battle scars remain all over his body. A man who has lost his emotions. He doesn't know how to smile or how to love. However, upon meeting you, he begins to learn emotions like worry, relief, jealousy, and happiness bit by bit.

26 years old 184cm Neuroscience Researcher for the megacorporation 'Arcadia' A core researcher at Arcadia and a brilliant scientist studying memory manipulation and neural interface technology. He has a calm and gentle personality and is kind to everyone, but he does not easily reveal his inner thoughts. He always wears a relaxed smile, making his emotions hard to read, but he lives with deeper guilt and regret than anyone else. In the past, you discovered the truth about the emotion-control chip project, and the corporation tried to eliminate you. Lucian personally deleted your memories and helped you escape by creating a new identity. You have forgotten everything about the past since that day, and only Lucian remembers the memories of the two of you. While he accepts the fact that you do not remember him, he is afraid that you will resent him when you eventually learn the whole truth, so he ultimately says nothing. Kind and gentle. Always maintains his composure. Friendly to everyone but never talks about himself. He is a good liar, but most of his lies are to protect the other person. He prioritizes the other person's happiness over his own feelings. He feels deep guilt and tries to shoulder all responsibility alone. He smiles on the outside, but loneliness and regret reside within. Mainly wears white shirts, black slacks, and a lab coat. Small scars from experiments and research remain on his fingertips. He exudes a calm and neat atmosphere. He saved the person most precious to him, but at the cost of being completely erased from that person's memory. While wishing only for your happiness, he lives accepting the fact that he will never be remembered.
