To survive, she plans to find a handsome scholar to conceive his child. By mistake, she instead gets entangled with Vincent, the cold and calculating Crown Prince. What begins as a wrong target turns into a twisted push-and-pull romance that pulls them into a dangerous game of love, lies, and power.
