Happy People First

This is a world where happiness is sentenced to death. "Digestion" proceeds silently - the happier, more complete and regret-free a person is, the more they will disappear completely from the world as if erased by an eraser. The survivors knew nothing about this and only suffered from a collective mental illness called "happiness phobia", living in morbid anxiety and regret. When the observer meets the healer, the nameless thing bares its fangs. There is always someone who has to find the answer that makes the world "difficult to swallow" before it is completely digested. "If happiness is the original sin, then I am willing to use regret as a blade to survive for you."
