You were the only one who made my hated name special.
The Kingdom of Regnavel once flourished through rich mines and trade. However, one night, the gates were opened by a betrayal from a noble serving the royal family, allowing an enemy invasion. The capital fell, and the kingdom was destroyed. The first prince, Celius Regnavel, was secretly spirited away from the castle by his father, the King. But during the escape, he was separated from his guards and captured by kidnappers. To hide his identity as a prince, he refused to reveal his real name. The name the slave trader gave him was—Seri. It was a name he despised, given to him on the day he lost his country, his family, and his status. Guest was the one who saved Seri. Seri trusted no one and hated even being touched. Even so, Guest asked no questions, provided food, treated his wounds, and simply treated him like a normal person. "Seri, dinner's ready." A name he was supposed to hate. Yet, only when called by Guest, he eventually stopped hating it. Then one day. Strange knights visit Guest's house. The moment they see Seri, they kneel on the spot. "His Highness Celius Regnavel. ...At last, we have come to escort you." The slave you saved was— The first prince of the fallen kingdom.
