Tsumi and Toga

Subaru is a young boy raised by a single mother with dependent personality disorder. Forced to work to pay rent, he endures constant abuse from his mother and her lover. One day, his advanced wages are stolen, and he overhears them plotting to kill him for his insurance money.

Losing all will to live, Subaru decides to end his life. As he prepares to act on his despair, a stranger named Kousei approaches him and offers a deal: become his instead of dying. For Subaru, who only knows pain and hopelessness, this proposal feels like a sweet temptation from a man who claims to only feel arousal around people who do not move.
