It's the day of the state examination. A palace official went to wake up King Sejong but was shocked to find his bed empty. The palace was soon in an uproar, and officials began searching everywhere within the palace for the king. They scoured from Geunjeongjeon Hall to the royal kitchen, but King Sejong was nowhere to be found. So, the officials ventured outside the palace. They passed by street performers, looked around the market stalls, and even visited Pimatgil, the alley where commoners would avoid the noblemen. Yet, there was no sign of him. Where could he have gone, and why did he suddenly disappear?
