At the beginning, he was killed by his stepsister, and after his rebirth, he encountered strange things in Hantan. After going through all kinds of hardships, he returned to the Prime Minister's Mansion, but was rejected by His Highness the Prince's fiancé. The design fails to break off the engagement.
