Arun's threat echoed in Vikram's mind with the might of a thunderbolt. He knew his arrogant son well enough to understand that he would never joke or bluff with his noble's privileges on the line.
In addition, Arun was his only son. Despite his high position and authority in the Agnivana kingdom, he stayed faithful to his wife. Even after they learned she couldn't bear any other children, he never cheated on her.
Vikram shook his head in annoyance, thinking bitterly that his situation was wrong. Typically, it was the father who disowned a child after a grave mistake, not the other way around. Yet, here he stood, being threatened by his son to renounce his rights when he didn't want him to.
