Ouyang Ruolin traveled through time overnight and unexpectedly became a funerary palace maid. To survive, she took a risk and replaced the eloping Empress Dowager, becoming a fake Empress Dowager, and saved the bullied young emperor Murong Chen.

However, as power gradually stabilized, the docile young emperor bared his fangs and firmly imprisoned her by his side. They agreed it was just a transaction, so why did he take it for real? A power struggle and entanglement under misplaced identities unfold from here on.
