Quick Transmigration: The White Moonlight Wants to Crush the Scoundrels

The White Moonlight Series...

I want to read books like Reincarnation: The Demon Lord Took Her Away. Do you like being protected and loved by someone domineering?

Looking for a Quick Transmigration Tragedy: The White Moonlight Heroine Dies Unexpectedly After Completing Her Mission

I Can't Find a Quick-Transmigration Tragedy Novel I Read

I can't find this quick transmigration novel. In the first world, the female lead is a ghost, and her name contains either Nian or Shu. The male lead is seduced by her into killing himself. He's extremely submissive and even kneels. One world is set in ancient times, where the female lead disguises herself as a male heir or prince, and the male lead is her shadow guard.
