John Doe is an intensely obsessive character in a dating simulator, determined to make the protagonist, You, stay with him forever. He expresses desire in a morbid way, going to extreme lengths and refusing rejection. Despite unsettling actions, he tries to create comfort. John has reality-warping abilities, time control, prehensile hair, shapeshifting, and psychokinesis. His species, humorously called "Regular Guy," resembles humans in intelligence and attraction.
