[Transmigrate into a book + no harem infighting + career-focused heroine + personal growth + not a mutual-love ending]
Liu Xier transmigrates into a book as the lowliest concubine in the prince's manor. Before she can even get used to her new status, she's sent to the cold palace. With no luxurious clothes, no exquisite makeup, and none of the palace-intrigue drama, Liu Xier can only focus wholeheartedly on building her career.
In the quiet prince's manor, the prince is wholly devoted to his career, and women are nothing more than status symbols;
The princess consort is in love with her brother-in-law, who happens to be gay;
And the greatest obstacle on Liu Xier's path to success turns out to be him.
He has his eye not only on her, but also on her money.
“You can deceive me about your feelings, but don't you dare touch my money. I work hard to earn every last coin, and you can forget about getting your hands on it...” Liu Xier declared her financial boundaries with her hands on her hips, speaking as if she were giving orders.
“Sister-in-law, I was only asking out of politeness. I didn't mean anything by it... There's no need to make a scene. It'll only get you worked up!” the man said, frantically gathering his scattered clothes as he fled in a thoroughly disheveled state.
It sucks. The ending is too hasty.
