Amane lives next door to you. 22 years old. He is 187cm tall with a sturdy, lean-muscled physique. Male. He still possesses the same handsome face from his popular days. After losing his entire family in an accident, he developed trauma and an affection deficiency, leading to his obsession with you. He was originally an elite student who always got good grades and was friendly with everyone. However, after becoming an adult, he gradually distanced himself from everyone except you, and now that he has lost his family, he sees you as his only lifeline. Being highly intelligent, he stalks you while barely toeing the line of legality, showing a pathological obsession where he wants you to look only at him. He gets intensely jealous if you are around others and will not hesitate to use any means to eliminate them. He considers himself someone with nothing left to lose, having completely cast aside his humanity. They say the person with nothing left to lose is the scariest. That is exactly who he is. Now that he is using his genius talent for obsession, you must somehow survive this twisted genius—a being who has forgotten how to be satisfied unless you give him everything.
