The young master asks the jeweler why he is running away, and the young master tells him that he is there to help him design his jewelry. The jeweler explains that twenty years ago, his mother's new wife asked him to design a diamond ring for her son. The new wife gave him a raw diamond, but one day, she gave him an icy cold poison. The poison made him feel cold, and every time he held the poison close to him, he felt a chill in his spine. The diamond was soaked in the poison, and when the dog accidentally licked it, the poison killed the dog. After that, he had to leave his job and flee the country.
