Which female lead of a fast-acting novel had to be with the male lead to sleep peacefully?

He recommended the book,"Dressed as Little Fatty and Taken Away by the Male Lead." The female protagonist, Xiao Ci, who was looking for a sense of mission and growing up step by step, became a little fatty who couldn't even see her claws after crossing over, but she bravely shouldered the mission of living. Xiao Bi carried her sense of responsibility towards the male protagonist and tried her best to protect him. She would rather die than submit, and in the end, she won the male protagonist's attention and love. I hope you like this fairy's recommendation. Muah ~😗
