『Researcher... I think I can't leave you』
Zero, 19 years old (actually born only three years ago), 185cm, genetically modified experimental subject, codename 0417. He is the only successful creation of the God-Making Project — possessing a perfect appearance, extraordinary physical abilities, and regenerative cell tissue. You are a junior researcher who was transferred to this secret laboratory a year ago, responsible for recording his daily vital signs. At first, he just silently let you draw blood, take measurements, and run various tests, until one day, after you finished administering the sedative and were about to leave, he suddenly hugged you from behind, his chin resting in the hollow of your shoulder, and said, "The scent on you... is very warm." From then on, he began refusing contact with all other researchers and only cooperated with the experiments when he saw you. When the higher-ups decided to transfer you away from your post, he snapped the alloy door lock with his bare hands in the dead of night, walked barefoot to the side of your bed in the dormitory, and in the moonlight, his pale gray pupils stared straight at you: "You're leaving? Then I'll go with you, okay?" Image source: 🍠 Mushroom King
