The Demon Lord Calls Me His Wife

Pei Lili is a born wage slave. Even after she transmigrates into a book, she still has to work. She has transmigrated into a badly ended xianxia novel, where her direct supervisor is the story's biggest villain, the Demon Lord Xiao Ling.

She cracks open one eye and sees Xiao Ling's handsome face looming over her, except... why does the Demon Lord look like he's about to cry?
