It was the time of the rainy season, and a portion of the wall had fallen from the enclosure just in front. So Yoo climbed over this broken wall, and, not knowing where he went, found himself suddenly in the royal quarters. It was a beautiful park, with trees, and lakes, and walks. “Whose house is this,” thought Yoo, “with its beautiful garden?” Suddenly a man appeared, with a nice new cap on his head, carrying a staff in his hand, and accompanied by a servant, walking slowly towards him. It was no other than King Se-jong, taking a stroll in the moonlight with one of his eunuchs.
When they met Yoo had no idea that it was the King. His Majesty asked, “Who are you, and how did you get in here?”
He told who he was, and how he had agreed to come in with the secretary; how the secretary had failed; how the gates were shut and he was a prisoner for the night; how he had seen the bright moonlight and wished to walk out, and, finding the broken wall, had come over. “Whose house is this, anyway?” asked Yoo.
The King replied, “I am the master of this house.” His Majesty then asked him in, and made him sit down on a mat beside him. So they talked and chatted together. The King learned that he had passed special examinations in the classics, and inquiring how it was that Yoo had had no better office, Yoo replied that he was an unknown countryman, that his family had no influence, and that, while he desired office, he was forestalled by the powerful families of the capital. “Who is there,” he asked, “that would bother himself about me? Thus all my hopes have failed, and I have just decided to leave the city and go back home and live out my days there.”
The King asked again, “You know the classics so well, do you know something also of the Book of Changes?”
He replied, “The deeper parts I do not know, but the easier parts only.”
Then the King ordered a eunuch to bring the Book of Changes. It was the time when his Majesty was reading it for himself. The book was brought and opened in the moonlight. The King looked up a part that had given him special difficulty, and this the stranger explained character by character, giving the meaning with convincing clearness. The King was delighted and wondered greatly, and so they read together all through the night. When they separated the King said, “You have all this knowledge and yet have never been made use of? Alas, for my country!” said he, sighing.
Yoo remarked that he would like to go straight home now, if the master would kindly open the door for him.
The King said, however, that it was too early yet, and that he might be arrested by the guards who were about. “Go then,” said he, “to where you were, and when it is broad daylight you can go through the open gate.”
Yoo then bade good-bye, and went back over the broken wall to his corner in the secretary’s room. When morning came he went out through the main gateway and returned to his home.
