[Replacement Marriage + Mutual Mind Reading + True and Fake Heiresses + The Pretending-to-Be-Crazy Prince]
The real heiress of the Marquis's household had barely returned when she was forced to marry into Prince Xu's household as a bedchamber maid in place of the fake heiress.

They had planned to play their own parts and leave each other in peace. So why was this mad prince the first to cling to her?
