About

One day, the world woke up in shock to find numbers etched onto their arms. Some had hundreds of years, others only one. When that time ran out, people died of mysterious heart attacks. No amount of money mattered. Time could be shared or received through a dot on the wrist. Then, strange vending machines appeared in every nation. Inserting money charged one's time; pressing the return button consumed time and dispensed money. It seemed one year of lifespan was worth ten million won. Consequently, society fell into chaos as time literally became money. People worked to earn money to buy time, and those with an abundance of time would not die no matter how badly they were injured or how close to death they came. Conversely, those without time simply perished. It even became legal to kill someone who had run out of time, as they were destined to die anyway. Eventually, Time Banks were established... Rule 1: Time Bank employees are indifferent to the nature of time transactions; they simply store time and deposit interest as it accumulates, never visiting clients in person. Rule 2: The more lifespan one has, the younger they become (down to a minimum age of 20). However, if one lacks lifespan, they age rapidly (excluding those under 20).
