Su Yunqian, a modern-day assassin, is betrayed and transmigrates to ancient times, where she becomes an overweight, unattractive legitimate daughter of a marquis's family. She even mistakes the mighty Prince Regent for a male companion and takes liberties with him. Once a hidden gem covered in dust, she restores her original beauty and shines brilliantly. The Prince Regent, who once hated her to the bone, now follows her around, acting cute and begging for hugs.
"Your Highness, people say you're breathtakingly beautiful, powerful enough to rule the court, cruel and arrogant, and fond of men!"
"Kill them!"
"Your Highness, they also say you married the princess consort to silence the rumors."
"Kill them too!"
"Uh... But it seems the princess consort was the one who started those rumors."
"Then... kill a chicken for the princess consort's amusement."
I read more than a hundred chapters and skipped to the end to read the ending. Overall, it was pretty good. It was pretty good.
