The Tyrannical Prince and His Willful Young Wife

Lady Nuo Shu, the eldest daughter of the General's Mansion, refuses to marry the sickly Prince Si Mo and arranges for her half-sister Nuo Xi to take her place instead. Nuo Xi agrees to the marriage to escape the Nuo family's control. Prince Si Mo, investigating the truth behind his mother's murder while hiding his true power, suspects Nuo Xi is an assassin sent by the Honored Saint Prince on their wedding night. He intends to kill her but discovers she once saved his life, so he decides to keep her temporarily. Meanwhile, Nuo Xi plans to wait for Si Mo to die of illness so she can inherit the Prince's Mansion's wealth.
