Overbearing prince x clever wife.
When they met for the first time, she helped him, and took a couple of benefits. See you again!
He married her as his concubine, saying that he would entangle her for a lifetime.
“Your Highness, the little prince is still watching…”
“Just in time, the king has come to teach him how to be pet a wife.”
